CR submanifolds of the six-sphere

open access: yes, 2010
Let M be a Riemannian submanifold of the six dimensional sphere equipped with its almost complex structure J. It is natural to investigate submanifolds M according to their relations to J. If the tangent bundle of M is invariant for J, then M is an almost complex submanifold, and if J maps the tangent bundle into the corresponding normal bundle M is a ...

Contact CR-Submanifolds of Kenmotsu Manifolds

open access: yes, 2011
2000 Mathematics Subject Classification: 53C15, 53C42. In this paper, we research some fundamental properties of contact CR-Submanifolds of a Kenmotsu manifold. We show that the anti-invariant distribution is always integrable and give a necessary and sufficient condition for the invariant distribution to be integrable.

CR-submanifolds of Kaehlerian product manifolds

open access: yes, 2007
WOS:000255030700002 In this paper, the geometry of F-invariant CR-submanifolds of a Kaehlerian product manifold is studied. Fundamental properties of this type submanifolds are investigated such m CR-product, D(perpendicular to)-totally geodesic and mixed geodesic submanifold.
