题  目：Gradient shrinking Ricci solitons of half harmonic Weyl curvature

报告人：吴鹏(复旦大学)

摘  要： Gradient Ricci solitons are natural generalizations of Einstein manifolds, and they play important roles in the study of the Ricci flow. In this talk I will talk about the classification of radient shrinking Ricci solitons with half harmonic Weyl curvature. The basic idea of the proof, which is motivated by the study of Einstein four-manifolds, is to construct a weighted subharmonic harmonic function using the Weitzenbock formula for the half Weyl curvature and apply a weighted maximum principle. This is joint work with Jia-Yong Wu and William Wylie.
