Twisted product CR-submanifolds in a locally conformal Kahler space form

Abstract

Certain twisted product CR-submanifolds in a Kahler manifold

and some inequalities of the second fundamental form of these

submanifolds are presented ([

K. Matsumoto, and Z. Senturk, Certain twisted product CR-submanifolds in

a Kaehler manifold, Proc. of the conference RIGA 2011, Riemannian Geometry

and Applications, 2011.

]). Then the length of the second fundamental

form of a twisted product CR-submanifold in a locally conformal

Kahler manifold is considered (2013), ([

K. Matsumoto, and Z. Senturk, Twisted product CR-submanifolds in a locally

conformal Kaehler manifold, Publications de l'Institut Mathematique, vol. 94,

(2013) 131{140.

]).

In this paper, we consider the relation of the mean curvature and the

length of the second fundamental form in two twisted product CR-

submanifolds in a locally conformal Kahler space form.
