Abstract

The aim of this paper is characterize a class of contact metric manifolds admitting \ast-conformal Ricci soliton. It is shown that if a (2n+1)(2n + 1)-dimensional N(k)N(k)-contact metric manifold MM admits \ast-conformal Ricci soliton or \ast-conformal gradient Ricci soliton, then the manifold M is \ast-Ricci at and locally isometric to the Riemannian of a flat (n+1)(n + 1)-dimensional manifold and an nn-dimensional manifold of constant curvature 4 for n>1n > 1 and flat for n=1n = 1. Further, for the first case, the soliton vector field is conformal and for the \ast-gradient case, the potential function ff is either harmonic or satisfy a Poisson equation. Finally, an example is presented to support the results.
