Conformal vector fields on almost Kenmotsu manifolds

In this paper, first we consider that the conformal vector field X is identical with the Reeb vector field sigma and next, assume that X is pointwise collinear with the Reeb vector field sigma; in both cases it is shown that the manifold N2m+1 becomes a Kenmotsu manifold and N2m+1 is locally a warped product N' x (f) M-2m, in which M-2m indicate an almost Kahler manifold, with coordinate t, N' being the open interval and f = ce(t) for some c ( positive constant). Beside these, we establish that if a (k, p)'-almost Kenmotsu manifold admits a Killing vector field X, then either it is locally a warped product of an open interval and an almost Kahler manifold or X is a strict infinitesimal contact transformation. Furthermore, we also investigate eta-Ricci-Yamabe soliton with conformal vector fields on (k, p)'-almost Kenmotsu manifolds and finally, we construct two examples.
