报告题目：Geometric Capacity and Rigidity Theorem
报告专家：Lihe Wang, SJTU and University of Iowa
报告地点：阳明学院 303
报告简介：
We will introduce a geometric quantity of domain that is related with the usual capacity and has rigidity consequences. Namely that if a domain has the geometric capacity as that of a cone in each of the neighborhood near a point, then it must be a cone of the same solid angle. As a consequence, we will show that if its capacity has the of the half space near each of its boundary point, then it must be a half space. Regularity theorems are also discussed for some localized capacity conditions

报告题目：Global Wellposedness and Traveling Wave Solutions of PDE Models of Chemotaxis
报告专家：Tong Li, SJTU and University of Iowa
报告地点：阳明学院 303
报告简介：
We investigate global existence and long ime behavior of solutions for PDE models of chemotaxis. These models include the classical Keller-Segel model and its variations such as a model reflecting rotational chemotactic motion. Moreover, we establish the existence and the nonlinear stability of large-amplitude traveling wave solutions to the system of nonlinear conservation laws derived from Keller-Segel model.
