Totally umbilical lightlike submanifolds

1997
Following work of A. Bejancu and K. L. Duggal as well as his own previous research, the author defines the notion of totally umbilical lightlike submanifolds. He gives some examples of totally umbilical lightlike submanifolds and analyses totally umbilical lightlike submanifolds of Lorentzian manifolds and, in particular, of 4-dimensional Lorentz ...
