1. KENMOTSU MANIFOLDS WITH GENERALIZED TANAKA-WEBSTER CONNECTION.

Author

Ghosh, Gopal and Chand De, Uday

Subjects
*MANIFOLDS (Mathematics), *LAPLACIAN operator, *GEOMETRIC connections, *THEORY of distributions (Functional analysis), *HERMITIAN structures
Abstract

We study the g-Tanaka-Webster connection associated to a Kenmotsu structure. With the help of g-Tanaka-Webster connection we characterize Kenmotsu manifolds and find certain curvature properties of this connection on Kenmotsu manifolds. Finally an illustrative example is given to verify some results. [ABSTRACT FROM AUTHOR]

3. On LP-Sasakian Manifolds with a coefficient α Satisfying Certain Curvature Conditions.

Author

De, Krishnendu and Chand De, Uday

Subjects
*SASAKIAN manifolds, *CURVATURE, *EINSTEIN manifolds, *TENSOR algebra, *GEODESICS, *DIFFERENTIAL geometry
Abstract

The object of the present paper is to classify an LP-Sasakian manifold with a coefficient a satisfying certain curvature conditions. Also ℰ-concircularly flat and ø-concircularly flat LP-Sasakian manifold with a coefficient α have been studied. Finally, we have shown the applications of such a manifold in general relativity and cosmology. [ABSTRACT FROM AUTHOR]
