报告人:Prof. Zhiqiang WangUtah State University, USA

  目:Sign-changing solutions of coupled elliptic equations

  间:2020.10.10(星期六),09:00-10:00

  点:数学院南楼N202

  要:We report results on existence of sign-changing solutions for coupled nonlinear Schrodinger equations. Various techniques will be discussed for constructing sign-changing solutions for this class of systems for which it is important to distinguish different solutions due to the existence of a large number of different type of solutions.

  目:三体问题中变分极小轨道的几何性质

  间:2020.10.10(星期六),10:00-11:00

  点:数学院南楼N202

  要:变分法是研究三体问题的重要工具。通过引入新的坐标变换,我们首次发现并证明了固定边值问题中变分极小轨道一个全新的几何性质。事实上,这个性质可以用来研究几类周期轨道的存在性等相关问题。

题目: Some new existence results for the nonlocal coupled nonlinear elliptic systems

报告人:王俊教授 江苏大学

时间:20201010日,星期六, 11:00-12:00

地点:

摘要: In this talk, we first introduce the results of the uniqueness and convergence on equilibria of the Keller-Segel system with subcritical mass. Then we present some new results for the coupled nonlinear Hartree type system with nonlocal interaction.
