Totally umbilical CR-submanifolds of nearly K�hler manifolds
Geometriae Dedicata, 1994A classification theorem for totally umbilical CR-submanifolds of nearly- Kähler manifolds is obtained. The statement and the proof are similar to the corresponding ones in a Kählerian ambient.

Totally umbilical lightlike submanifolds
1997Following 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 ...
