Imperfect Fluid Generalized Robertson Walker Spacetime Admitting Ricci-Yamabe Metric

open access: yesAdvances in Mathematical Physics, 2021
In the present paper, we investigate the nature of Ricci-Yamabe soliton on an imperfect fluid generalized Robertson-Walker spacetime with a torse-forming vector field ξ.

On the relation between Ricci-Harmonic solitons and Ricci solitons

open access: yesJournal of Mathematical Analysis and Applications, 2017
Abstract Let ( M m , g i j ) and ( N n , h β γ ) be two Riemannian manifolds, and ϕ : M → N a smooth map. By definition, a gradient Ricci-Harmonic soliton satisfies (0.1) { R i j − α ∇ i ϕ ∇ j ϕ + ∇ i ∇ j f = λ g i j ;

η-Ricci Solitons on Sasakian 3-Manifolds

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper we study η-Ricci solitons on Sasakian 3-manifolds. Among others we prove that an η-Ricci soliton on a Sasakian 3-manifold is an η-Einstien manifold.

H-almost Ricci-Yamabe solitons in paracontact geometry [PDF]

open access: yesarXiv, 2021
In this article, we classify h-almost Ricci-Yamabe solitons in paracontact geometry. In particular, we characterize para-Kenmotsu manifolds satisfying h-almost Ricci-Yamabe solitons and 3-dimensional para-Kenmotsu manifolds obeying h-almost gradient Ricci-Yamabe solitons.

Topology of Kähler Ricci solitons

open access: yesJournal of Differential Geometry, 2015
We prove that any shrinking Kahler Ricci soliton has only one end, and that any expanding Kahler Ricci soliton with proper potential has only one end.

Almost $\eta-$Ricci Solitons on Pseudosymmetric Lorentz Sasakian Space Forms

open access: yesCommunications in Advanced Mathematical Sciences, 2023
In this paper, we consider pseudosymmetric Lorentz Sasakian space forms admitting almost $\eta-$Ricci solitons in some curvature tensors. Ricci pseudosymmetry concepts of Lorentz Sasakian space forms admits $\eta-$Ricci soliton have introduced according ...

On Submanifolds of Riemannian Manifolds Admitting a Ricci Soliton [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2019
The aim of this paper is to study the conditions under which a submanifold of a Ricci soliton is also a Ricci soliton or an almost Ricci soliton. We give here a classification for Ricci solitons and their submanifolds according to their expanding ...

Ricci soliton and Ricci almost soliton within the framework of Kenmotsu manifold

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
First, we prove that if the Reeb vector field $\xi$ of a Kenmotsu manifold $M$ leaves the Ricci operator $Q$ invariant, then $M$ is Einstein. Next, we study Kenmotsu manifold whose metric represents a Ricci soliton and prove that it is expanding ...

On Sasaki–Ricci solitons and their deformations [PDF]

open access: yesAdvances in Geometry, 2016
Abstract We extend to the Sasakian setting a result of Tian and Zhu about the decomposition of the Lie algebra of holomorphic vector fields on a Kähler manifold in the presence of a Kähler-Ricci soliton. Furthermore we apply known deformations of Sasakian structures to a Sasaki-Ricci soliton to obtain a stability result concerning ...
