$\ast$-conformal Einstein solitons on N(k)-contact metric manifolds

Abstract

The main goal of this paper is devoted to N(k)-contact metric manifolds admitting $\ast$-conformal Einstein soliton and also $\ast$-conformal gradient Einstein soliton. In this settings the nature of the manifold, and the potential vector field, potential function of solitons are characterized, and conditions for the $\ast$-conformal Einstein soliton to be expanding, steady, or shrinking are also given. Furthermore, the nature of the potential vector field is evolved when the metric g of N(k)-contact metric manifold satisfies $\ast$-conformal gradient Einstein soliton. Finally, an illustrative example of a N(k)-contact metric manifold is discussed to verify our findings.
