Constantin C\u alinDepartment of Mathematics, Technical University, 6600 Iasi, Romania
Abstract: We determine all the totally umbilical lightlike Monge hypersurfaces of $R^4_1$. This is done by using the Bejancu-Duggal method  of studying lightlike hypersurfaces and then integrating a system of partial differential equations.
Keywords: lightlike degenerate hypersurfaces, totally umbilical, screen distribution, lightlike transversal vector bundle
