Abstract: Gradient Ricci solitons often occur as singular models in Ricci flow, so it is interesting to understand the geometry and the classification of Ricci solitons. In particular, I will talk about a splitting structure of complete gradient Ricci soliton with nonnegative curvature, and also a rigidity theorem for codimension one complete shrinking gradient Ricci soliton in $R^{n+1}$ with nonnegative Ricci curvature. This is a joint work with P.Guan and P.Lu.
