Geometry of Almost Conformal Ricci Solitons on K-Contact Manifolds

open access: yesUkrainian Mathematical Journal
UDC 515.1 We study geometric aspects of an almost conformal Ricci soliton and an almost conformal gradient Ricci soliton on K-contact manifolds. Among others, we first obtain the nature of almost conformal Ricci soliton under the conditions: (i) the potential vector field is a contact vector field, and (ii) the potential vector field is pointwise ...

Ricci solitons on para-Kähler manifolds

open access: yes, 2019
The main purpose of the paper is to study the nature of Ricci soliton on para-Kähler manifolds satisfying some certain curvature conditions. In particular, if we consider certain pseudosymmetric and parallel symmetric tensor on para-Kähler manifolds we ...

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

open access: yesFacta 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.

Conformal gradient Ricci soliton on twisted product manifolds

open access: yesFilomat
The concept of a conformal Ricci soliton generalizes that of a Ricci soliton. Notably the conformal Ricci soliton is closely related to the conformal Ricci flow. This paper aims to characterize Riemannian manifolds that admit a conformal gradient Ricci soliton.

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

open access: yes
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.

Semi-conformal mappings and Ricci solitons

open access: yes, 2018
Dans cette thèse, nous étudions principalement les applications semi-conformes et leur influence sur la résolution de certaines équations géométriques importantes comme celle d’un soliton de Ricci et celle d’une application biharmonique. Dans la première

Cohomogeneity Two Ricci Solitons with Sub-Euclidean Volume

open access: yes
We introduce new families of four-dimensional Ricci solitons of cohomogeneity two with volume collapsing ends. In a local presentation of the metric conformal to a product, we reduce the soliton equation to a degenerate Monge-Ampère equation for the ...
