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.

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.

Local and global scalar curvature rigidity of Einstein manifolds [PDF]
An Einstein manifold is called scalar curvature rigid if there are no compactly supported volume-preserving deformations of the metric which increase the scalar curvature.

∗-Ricci Tensor on α-Cosymplectic Manifolds
In this paper, we study α-cosymplectic manifold M admitting ∗-Ricci tensor. First, it is shown that a ∗-Ricci semisymmetric manifold M is ∗-Ricci flat and a ϕ-conformally flat manifold M is an η-Einstein manifold. Furthermore, the ∗-Weyl curvature tensor

Bose–Einstein condensation on curved manifolds [PDF]
Here we describe a weakly interacting Bose gas on a curved smooth manifold, which is embedded in the three-dimensional Euclidean space. To this end we start by considering a harmonic trap in the normal direction of the manifold, which confines the three ...

ρ-Einstein Solitons on Warped Product Manifolds and Applications
The purpose of this research is to investigate how a ρ-Einstein soliton structure on a warped product manifold affects its base and fiber factor manifolds. Firstly, the pertinent properties of ρ-Einstein solitons are provided.

(k,μ)-Paracontact Manifolds and Their Curvature Classification
The aim of this paper is to study (k,μ)-Paracontact metric manifold. We introduce the curvature tensors of a (k,μ)-paracontact metric manifold satisfying the conditions R⋅P_*=0, R⋅L=0, R⋅W_1=0, R⋅W_0=0 and R⋅M=0.
