专家简介：Dr. Duong received his PhD degree from the University of California at San Diego in June, 2012. He was a visiting assistant from professor at University of California at Irvine from July, 2012 to June, 2015. Now he is a visiting assistant professor at Texas A&M at Quartar. Dr. Duong is very solid and
very active young mathematician, has published or will publish around 10 research papers in SCI journals in mathematics. His major research interests are in the areas of Several Complex variable, Cauchy-Riemann geometry and Complex geometry and related to Partial Differential Equations.
报告摘要：In this talk, we will discuss the notion of Schwarzian derivative associated to CR mappings, and more generally, the notion of Schwarzian tensor associated to pseudoconformal changes of pseudohermitian structures. We will show that these notions can be used to characterize the strictly pseudoconvex CR manifolds which are locally equivalent to the CR sphere. We will also discuss two rigidity results related to the corresponding Mobius equations on CR manifolds.
