Ricci Solitons in f-Kenmotsu Manifolds and 3-dimensional Trans-Sasakian Manifolds

In the Present paper we study Ricci solitons in trans-sasakian manifolds. In particular we consider Ricci solitons in f -Kenmotsu manifolds and we prove the conditions for the Ricci solitons to be shrinking, steady and expanding. Key words: Ricci solitons; f -Kenmotsu; Trans-Sasakian; Shrinking; Steady; Expanding
