Abstract

n this paper, we have studied generalized Sasakian space form admitting almost quasi-Yamabe soliton and gradient almost quasi-Yamabe soliton. It is shown that if a generalized Sasakian space form admits a closed almost quasi-Yamabe soliton, then either soliton vector field is pointwise collinear with $\zeta$ or the structure functions are connected by a relation. Next, it is proven that if the metric of a generalized Sasakian space form is a gradient almost quasi-Yamabe soliton, then either the gradient of $\psi$ is pointwise collinear with $\zeta$ or the structure functions are connected by a relation.

Keywords
