题目：K-Yamabe problems and related geometric inequalities 

摘要：We first recall the $\sigms_k$ Yamabe problem and study it in a larger cone. The corresponding Sobolev inequality holds then in the larger cone. We also prove a new type Sobolev inequality and consider a new type Yamabe problem involving $Q$-curvatures, which leads to many open problems. The talk bases on  joint work with Yuxin Ge and Wei Wei.
