报告题目:Entropy via preimage structure for maps报告人:朱玉峻(厦门大学) 报告时间:2020.06.17 9:30-11:00报告平台:腾讯会议,ID:610 178 094报告摘要:For noninvertible dynamical systems, we investigate entropyvia preimage sets. For a continuous map, we introduce a notion ofpointwise metric preimage entropy. For systems with uniform separation of preimages, we establish a variati...

报告题目:SQG Equation and A Singular Integral报告人: 酒全森教授 报告人单位: 首都师范大学报告时间:2020年1 月 7日 16:30-17:30报告地点: 沙河主楼E404摘要:The SQG equation (surface quasi-geostrophic equation) is an important model in geophysical flow. In this talk, we will first review some recent results on well-posedness of SQG. Then, we will show the approximation relations on the ...
报告题目:Some aspects of PDE analysis报告人:李从明 教授 报告人单位: 上海交通大学 和 University of Colorado报告时间:2020年1 月 8日 15:30-16:30 报告地点:沙河主楼E404 摘要:We mainly consider three basic types of qualitative analysis on nonlinear elliptic PDEs: a priori estimates, regularity, and classification/Liouville type theorems. We give a brief introduction on: some basic maxim...
