Grigori Yakovlevich

Grigori Yakovlevich Perelman (born in 1966) is a Russian mathematician who won the Fields Medal in 2006 for his work in the resolution of the conjecture of Poincaré, one of the most important mathematical problems of the twentieth century.

Biography

Perelman was born in Leningrad, Soviet Union (now St. Petersburg, Russia). He studied mathematics at the State University of Leningrad and graduated in 1986. Then, he worked at the Steklov Mathematics Institute of the Russian Academy of Sciences.

Mathematical contributions

Perelman is known for his work in the theory of geometry and topology. In particular, he resolved the conjecture of Poincaré, which establishes that any simply related and closed three -dimensional variety is homeomorphic to the three -dimensional sphere. This conjecture had been raised by Henri Poincaré in 1904 and had been the subject of study of many mathematicians for decades.

Fields Medal

In 2006, Perelman was awarded the Fields Medal, considered the "Nobel Prize for Mathematics", for his work in resolving Poincaré's conjecture. However, Perelman rejected the medal and the prize of 10,000 dollars that he entails, arguing that he did not need recognition and that the medal was not necessary for his work.

Legacy

Perelman's work has had a significant impact on the mathematical community and has opened new lines of research on geometry and topology theory. Its resolution of the Poincaré conjecture is considered one of the most important achievements in the history of mathematics.
