On Ricci Solitons and Curvature Properties of Doubly Warped Products with QSMC

Axioms
This paper explores the geometric interplay between the Levi–Civita connection and the quarter-symmetric metric connection on doubly warped product manifolds.

Geodesic-Einstein metrics and nonlinear stabilities

, 2018
In this paper, we introduce notions of nonlinear stabilities for a relative ample line bundle over a holomorphic fibration and define the notion of a geodesic-Einstein metric on this line bundle, which generalize the classical stabilities and Hermitian ...

Gravitation, electromagnetism and cosmological constant in purely affine gravity

, 2009
The Ferraris-Kijowski purely affine Lagrangian for the electromagnetic field, that has the form of the Maxwell Lagrangian with the metric tensor replaced by the symmetrized Ricci tensor, is dynamically equivalent to the metric Einstein-Maxwell Lagrangian,

RICCI DEFECTS OF MICROLOCALIZED EINSTEIN METRICS [PDF]

Journal of Hyperbolic Differential Equations, 2004
This is the third and last in our series of papers concerning rough solutions of the Einstein vacuum equations expressed relative to wave coordinates. In this paper we prove an important result, concerning Ricci defects of microlocalized solutions, stated and used in the proof of the crucial Asymptotics Theorem in [1].

Charged dust in higher curvature geometry

European Physical Journal C: Particles and Fields, 2022
We analyze the configuration of charged dust in the context of the higher dimensional and higher curvature Einstein–Gauss–Bonnet–Maxwell theory. With the prescription of dust, there remains one more prescription to be made in order to close the system of

Einstein warped product spaces on Lie groups

Cubo, 2022
We consider a compact Lie group with bi-invariant metric, coming from the Killing form. In this paper, we study Einstein warped product space, $M = M_1 \times_{f_1} M_2$ for the cases, $(i)$ $M_1$ is a Lie group $(ii)$ $M_2$ is a Lie group and $(iii ...

Logarithmically-concave moment measures I

, 2012
We discuss a certain Riemannian metric, related to the toric Kahler-Einstein equation, that is associated in a linearly-invariant manner with a given log-concave measure in R^n.

New Infinite Series of Einstein Metrics on Sphere Bundles from AdS Black Holes

, 2004
A new infinite series of Einstein metrics is constructed explicitly on S^2 x S^3, and the non-trivial S^3-bundle over S^2, containing infinite numbers of inhomogeneous ones.
