Abstract

In this paper, we investigate invariant Ricci solitons, an important subclass in the class of homogeneous Ricci solitons. A classification of invariant Ricci solitons on three-dimensional Lie groups with left-invariant Riemannian metric and semi-symmetric connection different from the Levi-Civita connection is obtained. It is proved that in this case there exist invariant Ricci solitons with non-conformally Killing vector field.
