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.

Contact totally umbilical submanifolds of a sasakian space form [PDF]
Annali Di Matematica Pura Ed Applicata, 1977 We define a notion of contact totally umbilical submanifolds of Sasakian space forms corresponds to those of totally umbilical submanifolds of complex space forms. We study a contact totally umbilical submanifold M of a Sasakian space form\(\overline M \left( c \right)\) (c ≠ −3) and prove that M is an invariant submanifold or an anti-invariant ...

Totally contact-umbilical semi-invariant submanifolds of a Sasakian manifold
SUT Journal of Mathematics, 2002The main result of this paper is that a proper, non-totally contact-geodesic, totally contact-umbilical semi-invariant \(m\)-dimensional (\(m>4\)) submanifold of a Sasakian manifold, must be a generalized Hopf manifold. Let \(M\) be an \(m\)-dimensional submanifold of a \((2n+1)\)-dimensional Sasakian manifold \((N,\phi,\xi,\eta,g)\).

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 ...

Totally Umbilical Slant Submanifolds of S - Manifolds
2019In this paper, we study slant submanifolds of S-manifolds which are totally umbilical. We show that every totally umbilical proper slant submanifold of a S-manifold is either totally geodesic or if submanifold is not totally geodesic then we derive a formula for slant angle.

Totally umbilical pseudo-slant submanifolds of a nearly cosymplectic manifold
2010Summary: We study totally umbilical pseudo-slant submanifolds of a nearly cosymplectic manifold. We have obtained a classification theorem for totally umbilical pseudo-slant submanifolds of a nearly cosymplectic manifold.
