ON THE ES CURVATURE TENSOR IN $g - ESX_n$

Abstract

This paper is a direct continuation of [1]. In this paper we investigate some properties of ES-curvature tensor of g − ESXn, with main emphasis on the derivation of several useful generalized identities involving it. In this subsequent paper, we are concerned with contracted curvature tensors of g − ESXn and several generalized identities involving them. In particular, we prove the first variation of the generalized Bianchi’s identity in g − ESXn, which has a great deal of useful physical applications.
