On existence of canonical screens for coisotropic submanifolds

On existence of canonical screens for coisotropic submanifolds

In this paper we study coisotropic lightlike submanifolds of a semi-Riemannian manifold. For a large variety of this class of submanifolds, we prove two theorems on the existence of integrable canonical screen distribution and canonical null transversal bundle subject to some reasonable geometric conditions.
