Kähler–Einstein metrics on Fano surfaces

Expositiones Mathematicae, 2012
In these notes we give an exposition of a result of G. Tian, which says that a Fano surfaces admits a Kahler-Einstein metric precisely when the Lie algebra of holomorphic vector fields is reductive.

Einstein like -para Sasakian manifolds

Kuwait Journal of Science, 2013
Einstein like  -para Sasakian manifolds are introduced. For an  -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.

Five-dimensional Kaluza-Klein Theory reformulated

Revista Técnica de la Facultad de Ingeniería, 2011
This paper presents a reformulation of the five-dimensional Kaluza-Klein theory. taking into consideration the fact that these five dimensions of space-time are present on the tangent bundle of the Principal Bundle (B). Tb1s reformulation is possible due

Some curvature tensors in N(k)-contact metric manifold

Bibechana, 2018
The purpose of this paper is to study W7and W9-curvature tensors on N(k)-contact metric manifolds. We prove that a N(k)-contact metric manifold satisfying the condition W7( xi,X).W9=0 is eta-Einstein manifold.
