Some Graph Type Hypersurfaces in a Semi-Euclidean Space

Authors: IKAWA TOSHIHIKO, HONDA KYOKO

Abstract: We consider some graph type hypersurfaces in a semi-Euclidean space $\Bbb R^{n+1}_{q}$ and give conditions of the dimension $n+1$ and the index $q$ when a hypersurface is lightlike, totally geodesic and minimal.

Keywords: graph, lightlike hypersurface, minimal, semi-Euclidean space, totally geodesic.
