Some curvature properties of generalized Sasakian-space-forms

Lobachevskii Journal of Mathematics

The object of the present paper is to study generalized Sasakian-space-forms satisfying the curvature condition P(ξ, Y) - W = 0. Moreover, φ-M-projectively semisymmetric and φ-pseudo-projectively semisymmetric generalized Sasakian-space-forms are also studied. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.
