Totally Geodesic Submanifolds in Tangent Bundle with g - natural Metric [PDF]

open access: yes, 2013
In the paper we investigate submanifolds in a tangent bundle endowed with g-natural metric G, defined by a vector field on a base manifold. We give a sufficient condition for a vector field on M to defined totally geodesic submanifold in (TM,G).

B.‐Y. Chen inequalities for semislant submanifolds in Sasakian space forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 27, Page 1731-1738, 2003., 2003
Chen (1993) established a sharp inequality for the sectional curvature of a submanifold in Riemannian space forms in terms of the scalar curvature and squared mean curvature. The notion of a semislant submanifold of a Sasakian manifold was introduced by J. L. Cabrerizo, A. Carriazo, L. M. Fernandez, and M. Fernandez (1999).

Constant mean curvature hypersurfaces with constant δ‐invariant

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 67, Page 4205-4216, 2003., 2003
We completely classify constant mean curvature hypersurfaces (CMC) with constant δ‐invariant in the unit 4‐sphere S4 and in the Euclidean 4‐space 𝔼4.

On sectional and bisectional curvature of the H‐umbilical submanifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 1, Page 17-27, 2002., 2002
Let M be an H‐umbilical submanifold of an almost Hermitian manifold M˜. Some relations expressing the difference of bisectional and of sectional curvatures of M˜ and of M are obtained. The geometric notion of related bases for a pair of oriented planes permits to write the second members in a completely geometrical form.

Totally real submanifolds of a complex space form

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 1, Page 39-44, 1996., 1996
Totally real submanifolds of a complex space form are studied. In particular, totally real submanifolds of a complex number space with parallel mean curvature vector are classified.

On Generic submanifolds of a locally conformal Kahler manifold with parallel canonical structures

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 331-340, 1995., 1993
The study of CR‐submanifolds of a Kähler manifold was initiated by Bejancu [1]. Since then many papers have appeared on CR‐submanifolds of a Kähler manifold. Also, it has been studied that generic submanifolds of Kähler manifolds [2] are generalisations of holomorphic submanifolds, totally real submanifolds and CR‐submanifolds of Kähler manifolds.

CR‐submanifolds of a locally conformal Kaehler space form

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 3, Page 511-514, 1994., 1992
(Bejancu [1,2]) The purpose of this paper is to continue the study of CR‐submanifolds, and in particular of those of a locally conformal Kaehler space form (Matsumoto [3]). Some results on the holomorphic sectional curvature, D‐totally geodesic, D1‐totally geodesic and D1‐minimal CR‐submanifolds of locally conformal Kaehler (1.c.k.)‐space from are ...
