摘 要：In this short seminar, I will basically introduce the positive mass theorem and related problems. In particular, the method of the Ricci flow will be discussed in detail. Finally, I will talk about my work on the regularity of the positive mass theorem and some previous results.

题 目：The blow-up analysis of an affine Toda system corresponding to superconformal minimal surfaces in S^4

摘 要：In this talk, we study the blow-up analysis of an affine Toda system corresponding to minimal surfaces into S^4.This system is an integrable system which is a natural generalization of sinh-Gordon equation. By exploring a refined blow-up analysis in the bubble domain, we prove that the blow-up values are multiple of $8\pi$. This is a joint work with Prof. Guofang Wang.
