Semi-conformal mappings and Ricci solitons

, 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

Conformal structures and solitons in pseudo-Riemannian geometry [PDF]

, 2023
This thesis is divided into three distinct parts, each exploring different aspects of mathematical structures. The first part focuses on the investigation of locally conformally flat structures on fourdimensional manifolds.

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Generalized Conformal Killing Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The subject of this study is almost contact complex Riemannian manifolds, also known as almost contact B-metric manifolds. The considerations are restricted to a special class of these manifolds, namely those of the Sasaki-like type, because of their ...

Geometry of Almost Conformal Ricci Solitons on K-Contact Manifolds

Ukrainian 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 ...

Generalized Cross-Curvature Solitons of 3D Lorentzian Lie Groups

Axioms
We investigate left-invariant generalized cross-curvature solitons on simply connected three-dimensional Lorentzian Lie groups. Working with the assumption that the contravariant tensor Pij (defined from the Ricci tensor and scalar curvature) is ...

Cohomogeneity Two Ricci Solitons with Sub-Euclidean Volume

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 ...

The Generalized Symmetric Non-Metric Connection and Its Applications to ∗-Conformal η-Ricci–Yamabe Solitons on α-Cosymplectic Manifolds

Axioms
This paper investigates the geometric properties of ∗-conformal η-Ricci–Yamabe solitons (∗-conformal η-RYS) on α-cosymplectic manifolds (α−CSM) equipped with a newly introduced connection known as the generalized symmetric non-metric connection (GSNMC ...

Applications semi-conformes et solitons de Ricci

, 2018
In this work, we primarily study semiconformal mappings and their influence in the resolution of important geometric equations, such as those for a Ricci soliton and those for a biharmonic maps.
