Shing-Tung YauBorn 4 Apr 1949.Chinese-born mathematician who was awarded the Fields Medal in 1982 for his work in partial differential equations and differential geometry. His work also has applications in topology, algebraic geometry, representation theory and general relativity. Working collaboratively with Richard M. Schoen, Yau solved a long-standing open problem in relativity theory, by showing the positivity of mass for space-time. As a consequence, Schoen and Yau were able to give the first rigorous demonstration of how black holes can be formed because of the condensation of matter. A black hole possesses a gravitational field so intense that no matter or radiation can escape from it. Yau was the 1997 National Medal of Science winner. |
