Certain Curvature Properties of Generalized Sasakian-Space-Forms

In this paper we study h-projectively semisymmetric, Φ-projectively semisymmetric, h-Weyl semisymmetric and Φ-Weyl semisymmetric non-Sasakian (κ,μ)-contact metric manifolds. In all the cases the manifold becomes an η-Einstein manifold. As a consequence of these results we obtain that if a 3-dimensional non-Sasakian (κ,μ)-contact metric manifold satisfies such curvature conditions, then the manifold reduces to an N(κ)-contact metric manifold. © 2012 The Korean Mathematical Society.

A classification of (Îº,Î¼)-contact metric manifolds

The object of the present paper is to study the nature of generalized Sasakian-space-forms under some conditions regarding projective curvature tensor. All the results obtained in this paper are in the form of necessary and sufficient conditions. © 2010 NISC Pty Ltd.
