Twisted product CR-submanifolds in a locally conformal Kähler space forms


Vittoria Bonanzinga, Koji Matsumoto




Certain twisted product CR-submanifolds in a Kähler manifold and some inequalities of the second fundamental form of these submanifolds are presented ([14]). Then the length of the second fundamental form of a twisted product CR-submanifold in a locally conformal Kähler manifold is considered (2013), ([15]). 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 Kähler space forms.
