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.
