On generalized G-recurrent manifolds [PDF]
Surveys in Mathematics and its Applications, 2021 In this paper, we define a type of Riemannian manifold called generalized G-recurrent manifold, and study the various properties of such a manifold. Among others, it is shown that if a generalized G-recurrent manifold is Einstein, then its associated 1 ...

Examples of Einstein manifolds in odd dimensions [PDF]
, 2011 We construct Einstein metrics of non-positive scalar curvature on certain solid torus bundles over a Fano Kahler-Einstein manifold. We show, among other things, that the negative Einstein metrics are conformally compact, and the Ricci-flat metrics have ...

Geometry of conformal η-Ricci solitons and conformal η-Ricci almost solitons on paracontact geometry
Open Mathematics, 2022 We prove that if an η\eta -Einstein para-Kenmotsu manifold admits a conformal η\eta -Ricci soliton then it is Einstein. Next, we proved that a para-Kenmotsu metric as a conformal η\eta -Ricci soliton is Einstein if its potential vector field VV is ...

Complete Riemannian manifolds admitting a pair of Einstein-Weyl structures [PDF]
Mathematica Bohemica, 2016 We prove that a connected Riemannian manifold admitting a pair of non-trivial Einstein-Weyl structures $(g, \pmømega)$ with constant scalar curvature is either Einstein, or the dual field of $ømega$ is Killing.

K\"{a}hler-Einstein metrics on strictly pseudoconvex domains [PDF]
, 2011 The metrics of S. Y. Cheng and S.-T. Yau are considered on a strictly pseudoconvex domains in a complex manifold. Such a manifold carries a complete K\"{a}hler-Einstein metric if and only if its canonical bundle is positive.

Einstein extensions of Riemannian manifolds [PDF]
Transactions of the American Mathematical Society, 2021 Given a Riemannian space N N of dimension n n and a field D D of symmetric endomorphisms on N N , we define the extension M M of N N by D D to be the Riemannian manifold of dimension n + 1 n+1

On some classes of mixed-super quasi-Einstein manifolds
Acta Universitatis Sapientiae: Mathematica, 2016 Quasi-Einstein manifold and generalized quasi-Einstein manifold are the generalizations of Einstein manifold. The purpose of this paper is to study the mixed super quasi-Einstein manifold which is also the generalizations of Einstein manifold satisfying ...
