GEOMETRY OF SEMI-INVARIANT COISOTROPIC SUBMANIFOLDS IN GOLDEN SEMI-RIEMANNIAN MANIFOLDS

Abstract

In this paper, we study semi-invariant coisotropic lightlike submanifolds of a golden semi-Riemannian manifold. We give some necessary and sufficient conditions on integrability of distibutions on semi-invariant coisotropic lightlike submanifolds of a golden semi-Riemannian manifold. We obtain some geometric results for coisotropic lightlike submanifolds of a golden semi-Riemannian manifold. Moreover, we give an example.
