| Research Abstract |
We have progressed the research on local and global properties of geometric invariants for spacelike submanifolds in anti de Sitter space-time and Minkowski space-time. As a consequence, we have introduced the notion of lightlike tightness for spacelike submanifolds. We have also determined the partial differential equations for Marginally trapped sufaces of graph type in Minkowski space-time.
