Query: Transversal Lightlike Submanifolds of Golden Semi Riemannian Manifolds   The Golden Ratio is fascinating topic that continually generated news ideas.
A Riemannian manifold endowed with a Golden Structure will be called a Golden
Riemannian manifold. The main purpose of the present paper is to study the
geometry of radical transversal lightlike submanifolds and transversal
lightlike submanifolds of Golden Semi-Riemannian manifolds. We investigate the
geometry of distributions and obtain necessary and sufficient conditions for
the induced connection on these manifolds to be metric connection.
