Some uniqueness results for Ricci solitons
The aim of this paper is to describe the relationship between different Ricci soliton structures on a fixed Riemannian manifold. In particular, the author proves that every complete Ricci soliton endowed with a non-Killing homothetic vector field has non-negative scalar curvature and a finite fundamental group.
