ON m-PROJECTIVE CURVATURE TENSOR OF GENERALIZED SASAKIAN-SPACE-FORMS [PDF]
Advances in Pure and Applied Mathematics, 2018 AbstractWe set a definition of a{(0,2)}-type tensor on the generalized Sasakian-space-forms. The necessary and sufficient conditions forW-semisymmetric generalized Sasakian-space forms are studied. Certain results of the Ricci solitons, the Killing vector fields and the closed 1-form on the generalized Sasakian-space-forms are derived.

Generalized Sasakian-space-forms [PDF]
Israel Journal of Mathematics, 2004 Generalized Sasakian-space-forms are introduced and studied. Many examples of these manifolds are presented, by using some different geometric techniques such as Riemannian submersions, warped products or conformal and related transformations. New results on generalized complex-space-forms are also obtained.
