$ N(\kappa)- $contact Metric Manifolds with Generalized Tanaka-Webster Connection

Abstract

In this paper we work on $N(\kappa)$-contact metric manifolds with a generalized Tanaka-Webster connection . We obtain some curvature properties. It is proven that if a $N(\kappa)$-contact metric manifold with generalized Tanaka-Webster connection is K-contact then it is an example of generalized Sasakian space form. Also we examine some flatness and symmetric conditions of concircular curvature tensor on a $N(\kappa)$-contact metric manifolds with a generalized Tanaka-Webster connection.
