报告题目：Volume renormalization and applications in CR geometry

摘要：We will talk about the volume renormalization for two cases which are related to the CR invariants of submanifolds in CR manifolds. One is of the solution to the singular CR Yamabe problem in  3 (real) dimensions. The coefficient of the log term of the volume is one of the two CR invariants for surfaces in 3-dim CR manifolds, introduced by Cheng. The other one is of the minimal surface in 2-dim asymptotic complex hyperbolic space, which turns out to be related to the curves called chain and pseudocircle on the boundary. This is a joint work with P Yang, JH Cheng and A Malchiodi.
