摘要： In this talk, I will focus on Ricci soliton with nonnegaitve Ricci curvature. In dimension 4, we prove some classification results. If moreover the soliton has constant scalar curvature, the soliton is more rigid. 

      I will talk more on this problem, in particular, we prove five dimensional shrinking solliton with scalar curvature 3/2 is isometric to R^2 \times S^3.
