摘要:In this talk, we will talk about the rotational symmetry of gradient steady ricci solitons with linear dacay. Perelmann conjectured that any 3-d nonflat noncollapsed steady ricci solitons must be rotationally symmetric. This conjecture has been solved by Brendle aroung 2012. Recently, we generalize this result to noncollapsed steady ricci solitons with nonnegative curvature operator in high dimensions in addition that the scalar curvature has linear decay. This is a joint work with Prof. Xiaohua Zhu.
