Riemannian submersions whose total manifolds admit a Ricci soliton

, 2019
In this paper, we study Riemannian submersions whose total manifolds admit a Ricci soliton. Here, we characterize any fiber of such a submersion is Ricci soliton or almost Ricci soliton.

RICCI SOLITONS AND RICCI BI-CONFORMAL VECTOR FIELDS ON THE MODEL SPACE $Sol^{4}_{0}$

Facta Universitatis, Series: Mathematics and Informatics
In this paper, we classify the Ricci solitons and the Ricci bi-conformal vector fields on model space $Sol^{4}_{0}$. We also show which of them are gradient vector fields and which one of those are Killing vector fields.

Clairaut conformal submersions from Ricci solitons

Turkish Journal of Mathematics
In this study, we investigate Clairaut conformal submersions in the context of total manifolds that support a Ricci soliton structure. We begin by deriving the scalar curvature and Ricci tensor expressions associated with these manifolds, and we establish criteria under which the fibres can be characterized as almost Ricci solitons or Einstein ...

Randers Ricci soliton homogeneous nilmanifolds

, 2021
Let $F$ be a left-invariant Randers metric on a simply connected nilpotent Lie group $N$, induced by a left-invariant Riemannian metric $\hat{\boldsymbol{a}}$ and a vector field $X$ which is $I_{\hat{\boldsymbol{a}}}(M)$-invariant.

About rigidity of gradient almost Ricci Soliton

, 2017
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESThis work is based on [1] and aims to show a result of rigidity for gradient almost Ricci soliton. We will prove that an almost Ricci soliton gradient with nonnegative scalar curvature,

Classification of Vector Fields and Soliton Structures on a Tangent Bundle with a Ricci Quarter-Symmetric Metric Connection

Consider TM as the tangent bundle of a (pseudo-)Riemannian manifold M, equipped with a Ricci quarter-symmetric metric connection (Formula presented.). This research article aims to accomplish two primary objectives.

Clairaut anti-invariant Riemannian maps with Kähler and Ricci soliton structures [PDF]

The aim of this article is to explore the Clairaut anti-invariant Riemannian maps from/to Kähler manifolds admitting Ricci solitons. We find the curvature relations and calculate the Ricci tensor under different conditions. We discuss the condition under
