On Locally Conformally Flat Gradient Steady Ricci Solitons

arXiv:0909.2833

Abstract

In this paper, we classify n-dimensional (n>2) complete noncompact locally conformally flat gradient steady solitons. In particular, we prove that a complete noncompact non-flat conformally flat gradient steady Ricci soliton is, up to scaling, the Bryant soliton.
