报告摘要
Abstract: S. S. Chern was a leader of global differential geometry in the 20th century.
Since 1950 the subject has seen dramatic developments particularly through the
introduction of deep analytic methods. In the first lecture we will highlight some of the main problems of differential geometry. In the second lecture we will survey some of the deep problems which have been solved by variational techniques, and we will briefly describe some of the important geometric variational problems including the Plateau problem and the Yamabe problem. In the third lecture we will introduce geometric flows including the Ricci flow and survey some of the results achieved by flow methods.
The first lecture is intended for a general audience with little mathematical training.
The second and third should be accessible to a general mathematical audience including advanced undergraduate math majors.
报告人介绍：
Richard M. Schoen教授1950年10月23日出生于美国俄亥俄州的Fort Recovery市。他于1977年从斯坦福大学获得博士学位，现在是该校的Anne T.和Robert M. Bass人文和科学教授。Schoen教授是微分几何和广义相对论方面的著名专家。1979年，他和丘成桐教授一起，证明了广义相对论中的正能量定理。1984年，他得到了紧流形上Yamabe问题的完全解。这一研究将他之前和丘教授在研究中发展的新观点，以及Thierry Aubin 和 Neil Trudinger的研究成果结合了起来。2007年，他和Simon Brendle用Hamilton的Ricci flow证明了著名的1/4-pinching 微分球定理，从而在正截面曲率流形的研究中做出了基础性贡献，使得这一长达50年的问题得以解决。此外，Schoen教授还在1983年获得了MacArthur研究基金，在1989年获得了Bocher纪念奖，并在1996年获得了Guggenheim研究基金。现在，他是美国国家科学院院士和美国艺术和科学院院士。
Introduction of Speaker
Professor Richard M. Schoen was born on October 23, 1950 in Fort Recovery, Ohio.He received his PhD in 1977 from Stanford University where he is currently the Anne T.and Robert M. Bass Professor of Humanities and Sciences.Professor Schoen is a world leading expert in differential geometry and general relativity.In 1979, together with Shing-Tung Yau, he proved the fundamental positive mass theorem in general relativity. In 1984, he obtained a complete solution to the Yamabe problem on compact manifolds. This work combined new techniques with ideas developed in earlier work with Yau, and partial results by Thierry Aubin and Neil Trudinger. More recently, using Hamilton's Ricci flow, Simon Brendle and Richard Schoen in 2007 proved the famous 1/4-pinching differentiable sphere theorem, a fundamental result in the study of manifolds of positive sectional curvature which was open for about 50 years. Professor Schoen received a MacArthur Fellowship in 1983, the Bocher Memorial Prize in 1989, and won a Guggenheim Fellowship in 1996. He is a member of the US National Academy of Sciences and the American Academy of Arts and Sciences.
