On Ricci Riemannian Manifolds

Annals of the Alexandru Ioan Cuza University - Mathematics, 2010
Summary: The object of this paper is to study some properties of a type of Riemannian manifold called Ricci Riemannian manifold \((M^n,g),n>2\). The perfect fluid space time \((M^4,g)\) of general relativity is also studied.

Comparative Studies of Some Topological Properties on Hyperspaces of Convex Bodies and Wasserstein Hyperspace Associated with Riemannian Manifold

Journal of Applied Sciences and Environmental Management
The topological properties of some Gromov–Hausdorff hyperspaces of convex bodies associated with Riemannian manifold have been investigated, however, the objective of this paper is to provide a comparative studies of some topological properties on ...

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.
