Abstract

We deal with a submanifold of a Ricci soliton $(\bar{M},\bar{g},V,\lambda)$ and obtain

that under what conditions such a submanifold is Ricci soliton. Moreover, we establish some inequalities for Ricci solitons to obtain the relationships between the intrinsic or extrinsic invariants.

Keywords
