Hemi-Slant Submanifolds of A Locally Conformal Kaehler Manifold

, 2015
In the present paper, we study hemi-slant submanifolds of a locally conformal Kaehler manifold. We give conditions for the integrability of anti invariant and slant distributions which are involved in the definition of hemi slant submanifold.

PeV-Scale SUSY and Cosmic Strings from F-Term Hybrid Inflation

Universe
We consider F-term hybrid inflation (FHI) and SUSY breaking in the context of a B−L extension of the MSSM that largely respects a global U(1)R symmetry.

TOTALLY UMBILICAL CR-SUBMANIFOLDS OF A KAEHLER MANIFOLD

Tamkang 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 ...

On Locally Conformal Kaehler Submersions [PDF]

We study locally conformal Kaehler submersions, i.e., almost Hermitian submersions whose total manifolds are locally conformal Kaehler. We prove that the vertical distribution of a locally conformal Kaehler submersion is totally geodesic iff the Lee ...

Complex Osserman Kaehler Manifolds

, 2010
Let H be a 4 dimensional almost Hermitian manifold which satisfies the Kaehler identity. Then H is complex Osserman if and only if H has constant holomorphic sectional curvature. We also classify in arbitrary dimensions all the complex Osserman Kaehler manifolds which do not have 3 eigenvalues.

Slant submanifolds of Kaehler product manifolds

, 2007
In this paper, we study slant submanifolds of a Kaehler product manifold. We show that an F-invariant slant submanifold of Kaehler product manifold is a product manifold.

On Calabi's Inhomogeneous Einstein-Kaehler Manifolds [PDF]

Proceedings of the American Mathematical Society, 1977
We use some information on Lie groups to replace a long computation of Calabi, proving that certain complete Einstein-Kaehler manifolds are not locally homogeneous, and finding their isometry groups.
