Chung Tao Yang

from Wikipedia, the free encyclopedia

Chung-Tao Yang (born May 4, 1923 in Pingyang ; † 2005 ) was a Chinese - American mathematician who dealt with topology (general topology, differential topology, algebraic topology) and differential geometry .

Yang graduated from Zhejiang University with a bachelor's degree in 1946 with Su Buqing . He was an assistant there until 1948 and at the Chinese Academy of Sciences in 1948/49. In 1949/50 he was a lecturer at the National University of Taiwan and received his doctorate in 1952 from Tulane University under Alexander Wallace ( Equivalence of the Alexander-Kolmogorov and Cech Cohomology Theories ). From 1952 he was at the University of Illinois and from 1954 to 1956 at the Institute for Advanced Study , where his long-term collaboration with Deane Montgomery began. In 1956 he became an assistant professorand 1961 professor at the University of Pennsylvania , where he headed the mathematics faculty from 1978 to 1983. In 1991 he retired.

In 1980 he proved the case of odd dimensions in a conjecture by Wilhelm Blaschke about the characterization of the n-dimensional sphere as a reunion manifold. Jerry Kazdan , Marcel Berger and Alan Weinstein proved the case of even dimensions . He worked with Deane Montgomery on effects of groups on manifolds in differential topology. In the beginning he also dealt with finite projective geometry.

In 1968 he became a member of Academia Sinica , whose mathematics institute he advised from 1992.
