$m$-quasi-$*$-Einstein contact metric manifolds
The goal of this article is to introduce and study the characterstics of $m$-quasi-$*$-Einstein metric on contact Riemannian manifolds. First, we prove that if a Sasakian manifold admits a gradient $m$-quasi-$*$-Einstein metric, then $M$ is $\eta ...

A Kenmotsu metric as a conformal $\eta$-Einstein soliton [PDF]
The object of the present paper is to study some properties of Kenmotsu manifold whose metric is conformal $\eta$-Einstein soliton. We have studied certain properties of Kenmotsu manifold admitting conformal $\eta$-Einstein soliton.

Charged and Electromagnetic Fields from Relativistic Quantum Geometry [PDF]
In the recently introduced Relativistic Quantum Geometry (RQG) formalism, the possibility was explored that the variation of the tensor metric can be done in a Weylian integrable manifold using a geometric displacement, from a Riemannian to a Weylian ...

The $\eta$-Einstein condition on indefinite s-manifolds [PDF]
Abstract An η-Einstein condition is introduced in the context of indefinite globally framed f-manifolds, and several Schur-type results for indefinite S-manifolds are proved.

Einstein Manifolds As Yang-Mills Instantons [PDF]
It is well-known that Einstein gravity can be formulated as a gauge theory of Lorentz group where spin connections play a role of gauge fields and Riemann curvature tensors correspond to their field strengths.
