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 ...

Locally conformally flat ancient Ricci flows [PDF]

open access: yes, 2015
We show that any locally conformally flat ancient solution to the Ricci flow must be rotationally symmetric. As a by-product, we prove that any locally conformally flat Ricci soliton is a gradient soliton in the shrinking and steady cases as well as in ...

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.

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.

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 ...

n-Ricci-Bourguignon solitons with a semi-symmetric metric and semi-symmetric non-metric connection

open access: yesAIMS Mathematics, 2023
We consider a generalization of a Ricci soliton as $ \eta $-Ricci-Bourguignon solitons on a Riemannian manifold endowed with a semi-symmetric metric and semi-symmetric non-metric connection.

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 ...

Sufficient conditions for triviality of Ricci solitons

open access: yesAIMS Mathematics
We found conditions on an $ n $-dimensional Ricci soliton $ \left(M, g, \mathbf{u}, \lambda \right) $ to be trivial. First, we showed that under an appropriate upper bound on the squared length of the covariant derivative of the potential field $ \mathbf{
