Grigory Perelman biography. Grigory Yakovlevich Perelman biography. He did what was interesting to him

Grigory Yakovlevich Perelman was born on June 13, 1966 in Leningrad (now St. Petersburg) in the family of a mathematics teacher and an electrical engineer. From early childhood, Perelman became interested not only in mathematics, but also in music. His mother, Lyubov Leibovna, plays the violin beautifully, and it is thanks to her that the brilliant mathematician has retained his love for classical music to this day. My father taught me to play chess and gave me “Entertaining Physics,” which was popular in the last century.

The talented child studied in a regular Leningrad high school, located far from the city center, until the 9th grade. However, already in the 5th grade he actively attended the mathematics center, the head of which was S. Rukshin, associate professor of the Russian State Pedagogical University.

The first victory was won at the International School Olympiad in Mathematics in Hungary. The only award in his life that Perelman did not refuse is the gold medal, which he was awarded in Budapest. After 9th grade, G. Perelman studied at the 239th Leningrad Physics and Mathematics School. At the same time I went to music school. He did not receive a gold medal at the end of high school, since the not very athletic young man failed to pass the GTO standards. Today there is an unprecedented competition at the lyceum - up to ten people per place.

He received his higher education at the Faculty of Mathematics and Mechanics of Leningrad State University, where he was admitted without any exams. During the entire time he had an increased scholarship to them. V.I. Lenin. He graduated from the university with honors, and Perelman entered graduate school under his leadership. A.D. Alexandrov under LOMI, and later POMI. V. A. Steklova. After defending his dissertation for a candidate's degree (1990), he remains at his own university as a senior researcher.

At the dawn of the 90s, G. Ya. Perelman worked as a research assistant at several higher educational institutions in America - New York and Stony Brook. Since 1993, he has had a two-year internship in the same place where he writes a number of scientific papers. In 1994 he speaks at the Zurich IMC Congress. He is offered a job at Stanford, Tel Aviv, etc. Unassuming and simple in everyday life, the Russian scientist amazed his American scientific friends with his modesty, eating mostly bread and cheese and washing them down with milk.

In 1996, Perelman was awarded the European Society Prize for Young Mathematicians. The scientist does not accept it. In November 2002, Perelman blew up the minds of all mathematicians in the world. He publishes not somewhere in a reputable scientific journal, but directly on the Internet his conclusions on the Poincaré conjecture. Despite the lack of clear references and its brevity, the publication excited many. In 2003, Perelman gave lectures to US students and scientists about his work. Upon returning to St. Petersburg, the scientist stops all communication with former colleagues.

In 2005, Perelman stopped visiting his place of work, as they say, of his own free will, and in 2006, the proof of the St. Petersburg resident was recognized as the scientific breakthrough of the year, which happened for the first time in relation to “mental gymnastics”. Let us recall that the hypothesis about the probable forms of the Universe was put forward by a French mathematician a century ago. It was for her proof that Perelman was awarded the prestigious Fields Medal. There was a refusal from the Russian scientist. In March 2010, the Clay Mathematical Institute awarded him $1 million. Perelman also did not agree to accept them. Subsequently (2011) it was obtained by the Henri Poincaré Institute in Paris.

So, Perelman is the winner of three prizes, which he himself voluntarily refused. These include: awards of the European Mathematical Society (1996), Fields Medal (2006), Clay Mathematical Institute Millennium Prize (2010). In 2011, they decided to nominate Grigory Perelman from the St. Petersburg branch of the Mathematical Institute named after. Steklov into Russian academicians. The scientist did not give personal consent, they could not even find him, so at the moment the brilliant mathematician is not an academician.

The main work of the scientist is considered to be the Poincaré Hypothesis, but his work is not limited to this. There are three known articles, “The entropy formula for the Ricci flow and its geometric applications,” and the method of cognition itself is now called the Hamilton-Perelman theory. Previously, scientists proved the hypothesis about the soul (1994). Perelman is often credited with the authorship of the famous "Entertaining Physics". In fact, the author of the book is another person - Yakov Isidorovich Perelman (1882-1942).

The personality of G. Ya. Perelman is so unusual that a lot of jokes have already been invented about him. It is worth noting that the character of Perelman in these masterpieces of folk art is always characterized positively, and if they laugh at him, it is very kindly, as at a favorite fairy-tale hero. For example:

Sonya, are you aware that the mathematician Grigory Perelman has not indicated in any way his desire to become an academician of the Russian Academy. He didn't even respond to letters or calls.
- Apparently, at this time, as usual, mushrooms appeared...

In addition to funny stories, even proverbs and sayings appeared. Grigory Perelman's law: there is no offer that cannot be refused.

Today, the world-famous scientist lives in a modest St. Petersburg apartment in Kupchino with his old mother. However, at the place of registration on the street. He appears to Furshtatskaya extremely rarely, only to collect bills. He avoids journalists and communicates with few people. The scientist is still friends with his teacher and mentor, S. Rukshin, who works at Lyceum No. 239, and turns to him for advice. According to the latest data, the quiet genius Perelman is unemployed.

Grigory Perelman gained the reputation of an eccentric hermit and a strange person. Some even call him the St. Petersburg “rain man.” It’s probably not a matter of some disease, rumors about which journalists love to savor. It’s just that real science, which opens up new worlds for humanity, does not tolerate fuss. It is to Perelman that the words of his colleague at the institute Yu. Burago can be attributed: “Mathematics depends on depth.” The world-famous quiet genius rightfully ranks 9th among the hundred brilliant people of our time.

The hero of the new issue of the “Icon of the Era” column is Russian mathematician Grigory Perelman. What is known about him is that he gave up a million dollars by proving the Poincaré Conjecture, which, in turn, is known to be extremely difficult to understand. Moreover, the sequence here is exactly this - the fact of refusing money excited the respectable public much more than “some kind of abstract mathematical calculation.” Now that the hype around this decision has subsided, let’s figure out who Grigory Perelman is for mathematics and what mathematics is for him.

Grigory Perelman

Born in 1966 in Leningrad

mathematician

Life path

The Soviet Union had an outstanding mathematical tradition, so it is impossible to talk about Perelman's childhood without mentioning the phenomenon of Soviet mathematical schools. In them, talented children were trained under the guidance of the best mentors; such an environment served as fertile ground for future outstanding achievements. However, despite the competent organization of the learning process, there was also discrimination inherent in the Soviet system, when even having an unusual surname could cost a place in the city’s national team or admission to a university.

Henri Poincaré

Perelman grew up in an intelligent family and showed interest in mathematics from childhood. However, once he got into the mathematical circle, he did not immediately become a leader. The first failures spurred him to work harder and influenced his character - unyielding and stubborn. These qualities helped the scientist solve the main problem of his life.

Following a gold medal at the International Mathematical Olympiad in Budapest in 1982 and a brilliant graduation (there were not enough GTO standards passed for the gold medal) followed by Mathematical and Mechanics of St. Petersburg State University, and later graduate school, where Perelman also studied exclusively with “excellent” marks. When the Soviet Union ceased to exist, the scientist was faced with reality: science was experiencing a severe crisis. An internship in the USA unexpectedly took place, where the young scientist first met Richard Hamilton. The American mathematician made serious progress in solving the famous Poincaré problem. Moreover, he even outlined a plan, following which this decision could be reached. Perelman managed to communicate with him, and Hamilton made an indelible impression on him: he was open and spared no effort in explaining.

Institute building named after. Steklova in St. Petersburg

Despite offers to stay, at the end of the internship, Perelman returned to Russia, to his home apartment in a nine-story building in St. Petersburg in Kupchino (the notorious "ghetto" in the south of the city), and began working at the Mathematical Institute. Steklova. In his free time, he reflected on the Poincaré Hypothesis and the ideas that Hamilton had told him about. At this time, the American, judging by the publications, was unable to advance further in his reasoning. Soviet education gave Perelman the opportunity to look at the problem from the other side, using his own approach. Hamilton no longer responded to letters, and this became the “green light” for Perelman: he began working on solving the Hypothesis.

Every simply connected compact three-dimensional manifold without boundary is homeomorphic to a three-dimensional sphere.

The Poincaré conjecture belongs to topology - that branch of mathematics that studies the most general properties of space. Like any other branch of mathematics, topology is extremely specific and precise in its formulations. Any simplifications and retellings in a “more accessible form” distort the essence and have little in common with the original. That is why, in the framework of this article, we will not talk about the well-known thought experiment with a mug, which, through continuous deformation, turns into a donut. Out of respect for the main character, we simply admit that it is difficult to explain the Poincaré Hypothesis to people far from mathematics. And for those who are ready to devote time and effort to this, we will provide several materials for independent study.

The three-dimensional sphere is the object referred to in the formulation of the Poincaré Hypothesis

It took Perelman seven years to solve this problem. He did not recognize conventions and did not submit his works to scientific journals for review (a common practice among scientists). In November 2002, Perelman published the first part of his calculations on arXiv.org, followed by two more. In them, in an extremely condensed form, a problem even more general than the Poincaré Hypothesis was solved - this is the Thurston Geometrization Hypothesis, from which the first was a simple consequence. However, the scientific community received these works with caution. I was confused by the brevity of the solution and the complexity of the calculations that Perelman presented.

After the publication of the decision, Perelman again went to the United States. For several months he held seminars at various universities, talking about his work and patiently answering all questions. However, the main purpose of his trip was to meet with Hamilton. It was not possible to communicate with the American scientist a second time, but Perelman again received an invitation to stay. He received a letter from Harvard asking him to send them his resume, to which he irritably replied: “If they know my work, they don’t need my CV. If they need my CV, they don't know my work."

Fields Medal

The next few years were marred by an attempt by Chinese mathematicians to claim credit for the discovery.(their interests were supervised by Professor Yau, a brilliant mathematician, one of the creators of the mathematical apparatus of String Theory), the unbearably long wait for verification of the work, which was carried out by three groups of scientists, and the hype in the press.

All this went against Perelman’s principles. Mathematics attracted him with its categorical honesty and unambiguity, which is the basis of this science. However, the intrigues of his colleagues, concerned about recognition and money, shook the scientist’s faith in the mathematical community, and he decided not to study mathematics anymore.

And although Perelman’s contribution was eventually appreciated, and Yau’s claims were ignored, the mathematician did not return to science. No Fields Medal (analogous to the Nobel Prize for mathematicians), nor the Millennium Prize (million dollars) he didn't accept. Perelman was extremely skeptical about the hype in the press and minimized contacts with former colleagues. To this day he lives in the same apartment in Kupchino.

Timeline

Born in Leningrad.

As part of a team of schoolchildren, he participated in the International Mathematical Olympiad in Budapest.

Perelman was invited to spend a semester each at New York University and Stony Brook University.

Returned to the institute. Steklova.

november
2002 -
July 2003

Perelman posted three scientific articles on the website arXiv.org, which in an extremely condensed form contained a solution to one of the special cases of William Thurston’s Geometrization Hypothesis, leading to a proof of the Poincaré Hypothesis.

Perelman gave a series of lectures in the United States on his works.

Perelman's results were verified by three independent groups of mathematicians. All three groups concluded that Poincaré's Problem had been successfully solved, but Chinese mathematicians Zhu Xiping and Cao Huaidong, along with their teacher Yau Shintang, attempted plagiarism, claiming that they had found a "complete proof".

After graduating from school, without exams, he was enrolled in the Faculty of Mathematics and Mechanics of Leningrad State University (now St. Petersburg State University). During his student years, Perelman repeatedly won mathematics Olympiads. After graduating with honors from the university, he entered graduate school at the Leningrad branch of the Mathematical Institute. V.A. Steklov (since 1992 - St. Petersburg Department of the Mathematical Institute).

In 1990, he defended his Ph.D. thesis and was retained at the institute as a senior researcher.

In 1992, the scientist received an invitation to give a course of lectures at New York University and Stony Brook University, and then worked for some time at the University of Berkeley (USA). While in the USA, Perelman worked as a research fellow at American universities.
In 1996, he returned to St. Petersburg, where he worked at the St. Petersburg branch of the Mathematical Institute until December 2005.

Between November 2002 and July 2003, Perelman wrote three articles in which he revealed the solution to one of the special cases of William Thurston's geometrization conjecture, from which the validity of the Poincaré conjecture follows. The method of studying Ricci flow described by Perelman was called the Hamilton-Perelman theory, since the American mathematician Richard Hamilton was the first to study it.

Poincaré's conjecture was formulated by French mathematician Henri Poincaré in 1904 and is a central problem in topology, the study of the geometric properties of bodies that do not change when the body is stretched, twisted, or compressed. Poincaré's theorem was considered one of the unsolvable mathematical problems.

The mathematician is known for being emphatic and speaking publicly.

According to media reports, in 2014, Grigory Perelman received a Swedish visa for 10 years and moved to Sweden, where a local private company engaged in scientific development offered him a well-paid job. However, it was later reported that he lives in St. Petersburg, and visits Sweden as needed.

In 2011, it was published about the life and actions of the Russian scientist Grigory Perelman.

Russian mathematician, author of the proof of Poincaré's theorem - one of the fundamental problems of mathematics. Candidate of Physical and Mathematical Sciences. He worked at the Leningrad (St. Petersburg) department of the Steklov Mathematical Institute and taught at a number of US universities. Since 2003, he has not worked and hardly communicates with outsiders.

Grigory Yakovlevich Perelman was born on June 13, 1966 in Leningrad. His father was an electrical engineer who immigrated to Israel in 1993. Mother remained in St. Petersburg, worked as a mathematics teacher at a vocational school.

Perelman graduated from secondary school number 239 with in-depth study of mathematics. In 1982, as part of a team of schoolchildren, he participated in the International Mathematical Olympiad in Budapest. In the same year, he was enrolled in the Faculty of Mathematics and Mechanics of Leningrad State University without exams. He won faculty, city and all-Union student mathematical Olympiads. All the years he studied, he received a Lenin scholarship and graduated from the university with honors.

He entered graduate school at the Leningrad (now St. Petersburg) department of the Mathematical Institute. V. A. Steklov of the USSR Academy of Sciences (now RAS). Perelman's scientific supervisor was academician Alexander Danilovich Alexandrov. After defending his Ph.D. thesis, Perelman continued to work in the laboratory of mathematical physics at the Steklov Institute.

In 1992, Perelman was invited to spend a semester each at New York University and Stony Brook University, then continued teaching and research at Berkeley. In 1996 he returned to the Steklov Institute.

Perelman is known for his work on the theory of Alexandrov spaces and was able to prove a number of hypotheses.

In November 2002 - July 2003, Perelman posted three scientific articles on the website arXiv.org, which in an extremely condensed form contained a solution to one of the special cases of William Thurston's geometrization hypothesis, leading to a proof of the Poincaré conjecture. The proof of this theorem (which states that every simply connected closed three-dimensional manifold is homeomorphic to a three-dimensional sphere) is considered one of the fundamental problems of mathematics. The method of studying Ricci flow described by the scientist was called the Hamilton-Perelman theory. These works by Perelman did not receive the status of an official scientific publication, since arXiv.org is a library of preprints and not a peer-reviewed journal. Perelman made no attempts to officially publish these works.

In 2003, Perelman gave a series of lectures in the United States on his work, after which he returned to St. Petersburg and settled in his mother’s apartment in Kupchino. He resigned from his post as a leading researcher at the Laboratory of Mathematical Physics and almost completely cut off contacts with colleagues.

Over four years of checking and detailing Perelman’s calculations, leading experts in this field did not find any errors. On August 22, 2006, Perelman was awarded the Fields Medal "for his contributions to geometry and revolutionary achievements in understanding the analytical and geometric structure of the Ricci flow." Perelman refused to accept the award and communicate with journalists.

For the proof of Poincaré's theorem, the Clay Mathematical Institute (USA) awarded a prize of one million dollars. According to the prize's rules, Perelman can be awarded the award after publishing his work in a peer-reviewed journal.

Grigory Yakovlevich Perelman(b. June 13, 1966, Leningrad, USSR) - an outstanding Russian mathematician who was the first to prove the Poincaré conjecture.

Grigory Perelman was born on June 13, 1966 in Leningrad into a Jewish family. His father Yakov was an electrical engineer who immigrated to Israel in 1993. Mother, Lyubov Leibovna, remained in St. Petersburg and worked as a mathematics teacher at a vocational school. It was his mother, who played the violin, who instilled in the future mathematician a love of classical music.

Until the 9th grade, Perelman studied at a high school on the outskirts of the city, however, in the 5th grade he began studying at the mathematical center at the Palace of Pioneers under the guidance of RGPU associate professor Sergei Rukshin, whose students won many awards at mathematical Olympiads. In 1982, as part of a team of Soviet schoolchildren, he won a gold medal at the International Mathematical Olympiad in Budapest, receiving full marks for flawlessly solving all problems. Perelman graduated from the 239th Physics and Mathematics School in Leningrad. He played table tennis well and attended music school. I didn’t receive a gold medal only because of physical education, not passing the GTO standards.

He was enrolled in the Faculty of Mathematics and Mechanics of Leningrad State University without exams. He won faculty, city and all-Union student mathematical Olympiads. All the years I studied only with “excellent” marks. For academic success he received a Lenin scholarship. After graduating with honors from the university, he entered graduate school (headed by Academician A.D. Aleksandrov) at the Leningrad branch of the Mathematical Institute. V. A. Steklova (LOMI - until 1992; then - POMI). Having defended his Ph.D. thesis in 1990, he remained to work at the institute as a senior researcher.

In the early 1990s, Perelman came to the USA, where he worked as a research assistant at various universities, where his attention was drawn to one of the most difficult, at that time unsolved, problems of modern mathematics - the Poincaré Conjecture. He surprised his colleagues with his ascetic lifestyle; his favorite foods were milk, bread and cheese. In 1996, he returned to St. Petersburg, continuing to work at POMI, where he worked alone on solving the Poincaré Problem.

In 2002-2003, Grigory Perelman published his three famous articles on the Internet, in which he briefly outlined his original method for solving the Poincaré Problem:

The entropy formula for the Ricci flow and its geometric applications
Ricci flow with surgery on three-manifolds
Finite extinction time for the solutions to the Ricci flow on certain three-manifolds

The appearance on the Internet of Perelman's first article on the entropy formula for the Ricci flow caused an immediate international sensation in scientific circles. In 2003, Grigory Perelman accepted an invitation to visit a number of American universities, where he gave a series of talks on his work on the proof of the Poincaré Problem. In America, Perelman spent a lot of time explaining his ideas and methods, both in public lectures organized for him and during personal meetings with a number of mathematicians. After his return to Russia, he answered numerous questions from his foreign colleagues by email.

In 2004-2006, three independent groups of mathematicians were engaged in the verification of Perelman’s results: 1) Bruce Kleiner, John Lott, University of Michigan; 2) Zhu Xiping, Sun Yat-sen University, Cao Huaidong, Lehigh University; 3) John Morgan, Columbia University, Gan Tian, Massachusetts Institute of Technology. All three groups concluded that Poincaré's Problem had been successfully solved, but Chinese mathematicians Zhu Xiping and Cao Huaidong, along with their teacher Yau Shintang, attempted plagiarism, claiming that they had found a "complete proof". They later retracted this statement.

In December 2005, Grigory Perelman resigned from his post as a leading researcher at the Laboratory of Mathematical Physics, resigned from POMI and almost completely broke off contacts with colleagues.

He showed no interest in a further scientific career. Currently lives in Kupchino in the same apartment with his mother, leads a secluded lifestyle, ignores the press.

Scientific contribution

Main article: Poincaré conjecture

In 1994 he proved the hypothesis about the soul (differential geometry).

Grigory Perelman, in addition to his outstanding natural talent, being a representative of the Leningrad geometric school, at the beginning of his work on the Poincaré Problem also had a broader scientific outlook than his foreign colleagues. In addition to other major mathematical innovations that made it possible to overcome all the difficulties faced by mathematicians dealing with this problem, Perelman developed and applied the purely Leningrad theory of Alexandrov spaces to analyze Ricci flows. In 2002, Perelman first published his innovative work devoted to the solution of one of the special cases of William Thurston's geometrization conjecture, from which the validity of the famous Poincaré conjecture, formulated by the French mathematician, physicist and philosopher Henri Poincaré in 1904, follows. The method of studying the Ricci flow described by the scientist was called Hamilton-Perelman theory.

Recognition and ratings

In 1996 he was awarded the European Mathematical Society Prize for Young Mathematicians, but refused to receive it.

In 2006, Grigory Perelman was awarded the international Fields Medal Prize for solving the Poincaré conjecture (the official wording for the award: “For his contribution to geometry and his revolutionary ideas in the study of the geometric and analytical structure of the Ricci flow”), but he refused it too.

In 2006, Science magazine named the proof of Poincaré's theorem the scientific breakthrough of the year. Breakthrough of the Year). This is the first work in mathematics to earn this title.

In 2006, Sylvia Nasar and David Gruber published the article "Manifold Destiny", which talks about Grigory Perelman, his work on solving the Poincaré Problem, ethical principles in science and the mathematical community, and also contains a rare interview with him. The article devotes considerable space to criticism of the Chinese mathematician Yau Shintan, who, together with his students, tried to challenge the completeness of the proof of the Poincaré Hypothesis proposed by Grigory Perelman. From an interview with Grigory Perelman:

In 2006, The New York Times published an article by Dennis Overbye, “Scientist at Work: Shing-Tung Yau. The Emperor of Math." The article is devoted to the biography of Professor Yau Shintan and the scandal associated with accusations against him of attempts to belittle Perelman's contribution to the proof of the Poincaré Hypothesis. The article cites a fact unheard of in mathematical science - Yau Shintan hired a law firm to defend his case and threatened to prosecute his critics.

In 2007, the British newspaper The Daily Telegraph published a list of “One Hundred Living Geniuses”, in which Grigory Perelman ranks 9th. In addition to Perelman, only 2 Russians were included in this list - Garry Kasparov (25th place) and Mikhail Kalashnikov (83rd place).

In March 2010, the Clay Mathematics Institute awarded Grigory Perelman a US$1 million prize for his proof of the Poincaré conjecture, the first ever prize awarded for solving one of the Millennium Problems. In June 2010, Perelman ignored a mathematical conference in Paris, at which the Millennium Prize was supposed to be awarded for the proof of the Poincaré conjecture, and on July 1, 2010, he publicly announced his refusal of the prize, citing the following reasons:

Note that such a public assessment of the merits of Richard Hamilton by the mathematician who proved the Poincaré Hypothesis may be an example of nobility in science, since, according to Perelman himself, Hamilton, who collaborated with Yau Shintan, noticeably slowed down in his research, encountering insurmountable technical difficulties.

In September 2011, the Clay Institute, together with the Henri Poincaré Institute (Paris), created a position for young mathematicians, the money for which will come from the Millennium Prize awarded but not accepted by Grigory Perelman.

In 2011, Richard Hamilton and Demetrios Christodoulou were awarded the so-called. The $1,000,000 Shao Prize in Mathematics, also sometimes called the Nobel Prize of the East. Richard Hamilton was awarded for creating a mathematical theory, which was then developed by Grigory Perelman in his work to prove the Poincaré conjecture. It is known that Hamilton accepted this award.

Interesting Facts

In his work “The entropy formula for Ricci flow and its geometric applications” (eng. The entropy formula for the Ricci flow and its geometric applications) Grigory Perelman, not without humor, modestly points out that his work was partly financed by personal savings during his visits to the Courant Institute of Mathematical Sciences, the State University of New York (SUNY), the State University of New York at Stony Brook and the University of California in Berkeley, and thanks the organizers of these trips. At the same time, the official mathematical community allocated millions in grants to individual research groups in order to understand and test Perelman’s work.
When a member of the Stanford University hiring committee asked Perelman for C.V. (resume), as well as letters of recommendation, Perelman opposed:

The Manifold Destiny article was noticed by the outstanding mathematician Vladimir Arnold, who proposed reprinting it in the Moscow journal Uspekhi Matematicheskikh Nauk, where he was a member of the editorial board. The magazine's editor-in-chief, Sergei Novikov, refused him. According to Arnold, the refusal was due to the fact that the editor-in-chief of the magazine feared retaliation from Yau, since he also worked in the USA.
The biographical book of Masha Gessen tells about the fate of Perelman “Perfect severity. Grigory Perelman: genius and the task of the millennium", based on numerous interviews with his teachers, classmates, co-workers and colleagues. Perelman's teacher Sergei Rukshin was critical of the book.

Grigory Perelman became the protagonist of the documentary film “The Spell of the Poincaré Hypothesis” directed by Masahito Kasuga, filmed by the Japanese public broadcaster NHK in 2008.
In April 2010, the “Khrushchev Millionaire” episode of the talk show “Let Them Talk” was dedicated to Grigory Perelman. It was attended by Grigory’s friends, his school teachers, as well as journalists who communicated with Perelman.
In the 27th episode of “Big Difference” on Channel One, a parody of Grigory Perelman was presented in the hall. The role of Perelman was simultaneously performed by 9 actors.
It is a common misconception that the father of Grigory Yakovlevich Perelman is Yakov Isidorovich Perelman, a famous popularizer of physics, mathematics and astronomy. However, Ya. I. Perelman died more than 20 years before the birth of Grigory Perelman.
On April 28, 2011, Komsomolskaya Pravda reported that Perelman gave an interview to the executive producer of the Moscow film company President Film, Alexander Zabrovsky, and agreed to shoot a feature film about him. Masha Gessen, however, doubts that these statements are true. Vladimir Gubailovsky also believes that the interview with Perelman is fictitious.
