Ruled three-dimensional CR submanifolds of the sphere S6(1) [PDF]

open access: yes, 2017
We investigate proper, three-dimensional CR submanifolds of the nearly Kahler sphere S6(1) ruled by totally geodesic spheres S2(1), and classify them by using a sphere curve and a vector field along that curve.

Warped product CR-submanifolds of LP-cosymplectic manifolds [PDF]

open access: yes, 2010
In this paper, we study warped product CR-submanifolds of LP-cosymplectic manifolds. We have shown that the warped product of the type M = N(T) x (f)N(perpendicular to) does not exist, where N(T) and N(perpendicular to) are invariant and anti-invariant ...

Contact CR-warped product submanifolds in Kenmotsu space forms [PDF]

open access: yes, 2005
Recently, Chen studied warped products which are CR-submanifolds in Kaehler manifolds and established general sharp inequalities for CR-warped products in Kaehler manifolds.

TOTALLY UMBILICAL CR-SUBMANIFOLDS OF A KAEHLER MANIFOLD

open access: yesTamkang Journal of Mathematics, 1993
In the present paper we study totally umbilical CR-submanifolds of a Kaehler manifold. A classification theorem for a $D^\perp$-totally umbilical CR-submanifold is proved. The conditions under which a CR- submanifold becomes a CR-product are obtained, and finally a theorem for a CR-submanifold to be a proper CR-product is also ...

Screen Cauchy Riemann lightlike submanifolds [PDF]

open access: yes, 2005
We introduce a new class of lightlike submanifolds, namely, Screen Cauchy Riemann (SCR) lightlike submanifolds of indefinite Kaehler manifolds. Contrary to CR-lightlike submanifolds, we show that SCR-lightlike submanifolds include invariant (complex) and
