»ã±¨ÌáÒª£ºIn this talk, we will discuss the rigidity problem of steady Ricci solitons. We introduce a new curvature-pinching condition, which is weaker than one of the positive sectional curvature or the positive isotropic curvature, and prove several rigidity results for the rotational solutions, i.e., the Bryant soliton. This is a joint work with Ziyi Zhao.
