*-Ricci tensor on three dimensional almost coKähler manifolds

Abstract

In this paper, we obtain some classification results of three-dimensional non-coK?hler almost coK?hler manifold M whose Reeb vector field is strongly normal unit vector field with ?(???h?) = 0, for which the *-Ricci tensor is of Codazzi-type or M satisfies the curvature condition Q* ? R = 0.
