Lightlike Submanifolds of Metallic Semi-Riemannian Manifolds
Abstract
Our aim in this paper is to investigate
some types of lightlike submanifolds in metallic semi-Riemannian manifolds.
We study invariant and screen semi-invariant lightlike submanifolds of
metallic semi-Riemannian manifolds and give examples. We obtain the
conditions for the induced connection to be a metric connection. Also, we
find necessary and sufficient conditions for the distributions involved in
the definitions of such submanifolds to be integrable.
