Mathematics, 2019 In the present paper, we study conformal mappings between a connected n-dimension pseudo-Riemannian Einstein manifolds. Let g be a pseudo-Riemannian Einstein metric of indefinite signature on a connected n-dimensional manifold M.

On higher dimensional Einstein spacetimes with a warped extra dimension
, 2011 We study a class of higher dimensional warped Einstein spacetimes with one extra dimension. These were originally identified by Brinkmann as those Einstein spacetimes that can be mapped conformally on other Einstein spacetimes, and have subsequently ...

Projectively induced rotation invariant K\"ahler metrics
, 2016 We classify K\"ahler-Einstein manifolds which admit a K\"ahler immersion into a finite dimensional complex projective space endowed with the Fubini-Study metric, whose codimention is not greater than 3 and whose metric is rotation invariant.Comment: 9 ...

Differential Geometry and its Applications, 2017 The authors obtain some new naturally reductive and non naturally reductive left-invarant Einsein metrics on the exceptional Lie group \(E_7\). To this end, they consider a decomposition of the Lie algebra \(\mathfrak{g}=\mathfrak{e}_7\) by using the generalized Wallach space \(G/H=E_7/\mathrm{Spin}(8)\).

General Solutions of Braneworlds under the Schwarzschild Ansatz
, 2010 General solutions for braneworld dynamics coupled with the bulk Einstein equation are derived under the Schwarzschild ansatz. They relate the brane metric to the exterior configurations, and establish fine tuning conditions for the braneworlds to ...

QUASI-EINSTEIN CONTACT METRIC MANIFOLDS [PDF]
Glasgow Mathematical Journal, 2014 AbstractWe consider quasi-Einstein metrics in the framework of contact metric manifolds and prove some rigidity results. First, we show that any quasi-Einstein Sasakian metric is Einstein. Next, we prove that any complete K-contact manifold with quasi-Einstein metric is compact Einstein and Sasakian.

Existence of Generalized Maxwell–Einstein Metrics on Completions of Certain Line Bundles
MathematicsIn Kähler geometry, Calabi extremal metrics serves as a class of more available special metrics than Kähler metrics with constant scalar curvatures, as a generalization of Kähler Einstein metrics. In recent years, Maxwell–Einstein metrics (or conformally

On the Ricci Curvature of Normal-Metric Contact Pair Manifolds
Journal of New Theory, 2021 In this study, we work on normal-metric contact pair manifolds under certain conditions related to the Ricci curvature. We obtain some results for generalized quasi-Einstein normal-metric contact pair manifolds.
