Title: Sphere theorems for submanifolds in Kahler manifold
Abstract: In this talk, we will first recall the previous results on topological and differentiable sphere theorems, especially for submanifolds. Then we will talk about our recent result on submanifolds in Kahler manifold. This is joint work with Linlin Sun.

Title: Pohozaev type constants and applications in geometric analysis
Abstract: In this talk, we shall discuss the notion of Pohozaev type constants for solutions of some nonlinear elliptic systems in dimension two and explore their applications in the study of harmonic map type systems and Liouville type systems.
