Ricci Semi-Symmetric Lightlike Hypersurfaces of an Indefinite Cosymplectic Space Form
Gupta, Ram Shankar;

Abstract
This paper is devoted to study Ricci semi-symmetric lightlike hypersurfaces of an indefinite cosymplectic space form with structure vector field tangent to hypersurface. The condition for Ricci tensor of lightlike hypersurface of indefinite cosymplectic space form to be semi-symmetric and parallel have been obtained. An example of non-totally geodesic Ricci semi-symmetric lightlike hypersurface in $\small{R^7_2}$ have been given.
