An Inequality on Quaternionic CR-Submanifolds

open access: yesAnalele Universitatii "Ovidius" Constanta - Seria Matematica, 2018
Abstract We establish an inequality for an intrinsic invariant of Chen-type defined on quaternionic CR -submanifolds in quaternionic space forms, in terms of the squared mean curvature, the main extrinsic invariant, by using the method of constrained extrema.

Totally real submanifolds of the nearly kaehler 6-sphere [PDF]

open access: yes, 1997
Totally real 3-dimensiunal submanifolds of the nearly Kaehler 6-sphere are the main topic of this thesis. Having introduced preliminaries on the theory of complex and almost complex manifolds, the nearly Kaehler structure of S(^6) and the non existence ...

Micro-abrasion–corrosion of a Co–Cr/UHMWPE couple in Ringer's solution : an approach to construction of mechanism and synergism maps for application to bio-implants [PDF]

open access: yes, 2010
In studies of tribo-corrosion, the degradation of bio-materials has become of increasing research interest in recent years. This is because, in many cases, the interactions of the tribological and corrosion component in biological environments are not ...

On Warped Product Pointwise Pseudo-Slant Submanifolds of LCK-Manifolds and Their Applications

open access: yesAxioms
The concept of pointwise slant submanifolds of a Kähler manifold was presented by Chen and Garay. This research extends this notion to a more general setting, specifically in a locally conformal Kähler manifold. We study the pointwise pseudo-slant warped

CR‐submanifolds of a nearly trans‐Sasakian manifold [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
This paper considers the study of CR‐submanifolds of a nearly trans‐Sasakian manifold, generalizing the results of trans‐Sasakian manifolds and thus those of Sasakian 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 ...
