题目：A brief review onsome principal eigenvalue problems of elliptic and time-periodic parabolic operators

时间：13：30-14：30

摘要：

In this talk, we shall give a brief review on the progress of some principal eigenvalue problemsof a linear second order elliptic or time-periodic operator, which mainly focuses on the asymptotic behavior of the principal eigenvalue with respect tosome parameters such as the diffusion rate, large advection, etc. We are particularly interested in the role of boundary conditions and spatial/temporal degeneracies on the behavior of the principal eigenvalue.

题目：Positive solution of a coupled Schrodinger system with critical exponent

时间：14：30-15：30

摘要：

We establish the existence of a positive solution at high energy level for a coupled Schrodinger system with critical exponent. Our result extends the result of [Benci-Cerami,JFA, 1990] from a scalar field equation to a system. This is joint work with Prof. Zhaoli Liu.
