On M-Projective Curvature Tensor of Lorentzian α-Sasakian Manifolds

Full Text PDF

Abstract:

In this paper, we study the nature of Lorentzian α-Sasakian manifolds admitting M-projective curvature tensor. We show that M-projectively flat and irrotational M-projective curvature tensor of Lorentzian α-Sasakian manifolds are locally isometric to unit sphere Sn(c) , where c = α2. Next we study Lorentzian α-Sasakian manifold with conservative M-projective curvature tensor. Finally, we find certain geometrical results if the Lorentzian α-Sasakian manifold satisfying the relation M(X,Y)⋅R=0.
