CR-LIGHTLIKE SUBMANIFOLDS OF INDEFINITE PARA- SASAKIAN MANIFOLD [PDF]

, 2017
The purpose of this paper is to study a totally contact umbilical contact CR-lightlike submanifolds of an indefinite para-Sasakian manifold. In this paper, we prove that a totally contact umbilical CR-lightlike submanifold is totally contact geodesic ...

CR-submanifolds. A class of examples

, 2005
I present a class of examples of \CR-submanifolds of manifolds endowed with different structures, obtained as level sets of momentum maps associated to specific Hamiltonian actions.

\(CR\)-submanifolds of almost Hermitian manifolds

, 1994
\(CR\)-submanifolds are well studied in the case that \((M,g)\) is a Kähler manifold. In this paper, \((M,g)\), in general, is not Kähler. We examine the case of some classes of almost Hermitian manifolds, which generalize the Kähler case. In particular, the more interesting results are obtained for \(CR\)-submanifolds of quasi-Kähler, semi-Kähler, \({\
