Orientability of vector bundles over real flag manifolds
Vector bundles Orientability Flag manifold
2011/1/17
The purpose of this paper is to give necessary and sufficient conditions for the orientability of vector bundles over flag manifolds of real semi-simple Lie groups. We focus on two kinds of vector bun...
Slant submanifolds of Kaehler Product Manifolds
Slant Submanifold Kaehler Manifold Ricci tensor
2010/2/26
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. We also obtain some curvature...

We classify P-Sasakian manifolds, which satisfy the conditions Z(x ,X) · Z = 0, Z(x ,X) · R = 0, R(x ,X) · Z = 0, Z(x ,X) · S = 0 and Z(x ,X) · C = 0.
