Gang Tian (Chinese: 田刚; pinyin: Tián Gāng; 1958 -) is a Chinese mathematician and an academician of the Chinese Academy of Sciences. He is known for his contributions to geometric analysis and quantum cohomology, among other fields.

Mathematical contributions

Much of Tians earlier work was about the existence of Kähler-Einstein metrics on complex manifolds. In particular he solved the existence question for Kähler-Einstein metrics on complex surfaces, and showed that hypersurfaces with a Kähler-Einstein metric are stable in the sense of geometric invariant theory. Consider an m-dimensional manifold M with metric tensor g. ... In differential geometry, a complex manifold is a manifold such that every neighborhood looks like the complex n-space. ... In mathematics, the Enriques-Kodaira classification is a classification of compact complex surfaces. ... In mathematics, geometric invariant theory in algebraic geometry is a (technically complex) development building on nineteenth century invariant theory. ...

He also (jointly with Y. Ruan) showed that the quantum cohomology ring of a symplectic manifold is associative.

In 2006, he, together with John Morgan of Columbia University, gave a detailed proof of the Poincaré Conjecture, and thus helped to verify the proof by Grigori Perelman.[1] Columbia University is a private university whose main campus lies in the Morningside Heights neighborhood of the Borough of Manhattan in New York City. ...
