Here it is proved that a symmetric parallel second order covariant tensor in a -Kenmotsu manifold is a constant multiple of the metric tensor. Using this result, it is shown that if (LV g + 2S) is O-parallel where V is a given vector eld, then the structure (g; V; ) yields a Ricci soliton. Further, by virtue of this result, we found the conditions of Ricci soliton in -Kenmotsu manifold to be shrinking, steady and expending respectively. Next, Ricci soliton for 3-dimensional -Kenmotsu manifold are discussed with an example. 2023-08-13T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/776 Title: SEMI GENERALIZED ϕ-RECURRENT TRANS-SASAKIAN MANIFOLDS Authors: Kumar, Rajesh Abstract: In this paper we studied semi generalized '-recurrent and concircular '- recurrent Trans-Sasakian manifolds. 2020-05-01T00:00:00Z
