»ã±¨ÌáÒª£ºSteady Ricci solitons are important examples of singularities models. In higher dimensions, singularity models can be steady Ricci solitons on orbifolds. In this talk, we will review some rigidity theorems on positively curved steady Ricci solitons on manifolds. We will also classify positively curved noncollapsed steady Ricci solitons on orbifolds that dimension reduces to quotients of spheres.
