Grigori perelman biography of albert murphy

In , Perelman proved the soul conjecture.

Grigori Perelman (born , U.S.S.R.) is a Russian mathematician who was awarded—and declined—the Fields Medal in for his work on the Poincaré conjecture Missing: albert murphy.

In , he proved Thurston's geometrization conjecture. In August , Perelman was awarded the Fields Medal[1] for "his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow. Grigori's mother Lubov gave up graduate work in mathematics to raise him. Grigori's mathematical talent became apparent at the age of ten, and his mother enrolled him in Sergei Rukshin's after-school math training program.

His mathematical education continued at the Leningrad Secondary School , a specialized school with advanced mathematics and physics programs. Grigori excelled in all subjects except physical education.

Grigori Yakovlevich Perelman is a Russian mathematician and geometer who is known for his contributions to the fields of geometric analysis, Riemannian geometry, and geometric topology.

In , as a member of the Soviet Union team competing in the International Mathematical Olympiad, an international competition for high school students, he won a gold medal, achieving a perfect score. His dissertation was titled "Saddle surfaces in Euclidean spaces. In the late s and early s, Perelman held research positions at several universities in the United States.

Petersburg Mathematical Society for his work on Aleksandrov's spaces of curvature bounded from below. After having proved the soul conjecture in , he was offered jobs at several top universities in the US, including Princeton and Stanford, but he rejected them all and returned to the Steklov Institute in Saint Petersburg in the summer of for a research-only position.

He has a younger sister, Elena, who is also a scientist. She received a Ph. Until the autumn of , Perelman was best known for his work in comparison theorems in Riemannian geometry.
