Grigori Perelman

Grigori Yakovlevich Perelman is a Russian mathematician who was born on 13 June 1966 in Leningrad, the Soviet Union to Russian-Jewish parents. He made great contributions to geometric topology and Riemannian geometry.

Her mother, Lyubov was a mathematic graduate, but she gave up to raise him. 

He was a bright student. From the age of 10, he started showing his mathematical skill to the world. His mother, after-school mathematics training program, enrolled him in Sergei Rukshin. At the Leningrad Secondary School, he continued his mathematical education. This is a specialized school where advanced physics and mathematics are been taught. Grigori outshined in all subjects excluding physical education.

Grigori Yakovlevich Perelman life Milestones:

  1. In 1982, he won a gold medal while competing in the International Mathematical Olympiad as a member of the Soviet Union team. He was competing with international high school students.
  2. In the late 1980s and early 1990s, with a powerful endorsement from the geometer Mikhail Gromov, He got research positions at numerous universities in the United States. 
  3. In the 1990s, he made prominent contributions to the subject of Alexandrov spaces.
  4. After his PhD in 1990, He began to work at the USSR Academy of Sciences at the Leningrad Department of Steklov Institute of Mathematics.
  5. In 1991, for his work on Aleksandrov’s spaces of curvature, At the St. Petersburg Mathematical Society, he got the Young Mathematician Prize.
  6. In 1992, he was invited as a mathematics guest lectures in Stony Brook University and New York University. This is where he started working on Ricci curvature. 
  7. In 1993, At the University of California, Berkeley, he received Miller Research Fellowship for two-years.
  8. In 1994, he proved the soul conjecture in Riemannian geometry.
  9. In 1994, he got many job offers from top universities like Stanford and Princeton, but he rejected them all.
  10. In 1995, To continue his research work, He returned to the Steklov Institute in Saint Petersburg.
  11. In November 2002, He gave the first of three preprints to the arXiv.
  12. In 2002 and 2003, he developed new techniques in the analysis of Ricci flow, and presented a detailed picture of a proof of Thurston’s geometrization conjecture,
  13. In August 2006, for Perelman’s revolutionary insights into the geometric structure and the analytical and of the Ricci flow and his contributions to geometry, he was offered the Fields Medal.
  14. On 22 December 2006, the Scientific Journal Science appreciated Perelman’s proof of the Poincaré conjecture as the scientific “Breakthrough of the Year”. 
  15. This is the first such recognition in the field of mathematics.
  16. On 18 March 2010, It is said that he was about to get the first Clay Millennium Prize for solving the Poincaré conjecture.
