Generalized Sasakian-Space-Forms with Quasi-Conformal Curvature Tensor

Abstract

In this article, we study generalized Sasakian-space-form with quasi-con- formal curvature tensor. In a quasi-conformally °at generalized Sasakian-space- form we ¯nd some relations between di®erentiable functions f1, f2 and f3. In a quasi-conformally °at generalized Sasakian space form we also ¯nd Ricci- tensor, Ricci-operator and scaler curvature. Ricci-tensor, Ricci-operator and scalar curvature are also found in a quasi-conformally semi-symmetric general- ized Sasakian-space-form.
