On the Lie Foliation structure of Walker Manifolds

Ameth Ndiaye

We study Walker manifolds, that is, pseudo-Riemannian manifolds admitting a null parallel distribution $\D$ of rank . We show that $\D$ always integrate…

On the Classification of Non-Homogeneous Solvable Lie Foliations

Ameth Ndiaye

We study Lie foliations on compact manifolds whose transverse group is \emph{metabelian} (a natural generalization of the affine group $\GA$ considered in earlier work). We establi…

Rigidity of Nilpotent Lie Foliations: Cohomological Obstructions and Classification

Ameth Ndiaye

In this article, we develop a systematic cohomological framework for the study of the rigidity of nilpotent Lie foliations with respect to solvable deformations. We introduce the d…

Geometric study of non-constant vector fields making hyperbolic space Ricci-Bourguignon solitons

Mafal Ndiaye Diop, Abdou Bousso, Cheikh Khoule +1

The objective of this paper is to deepen the study of vector fields on hyperbolic spaces that transform them into a Ricci-Bourguignon soliton. Starting from a recent…

Ricci-Yamabe solitons on a Walker 3-manifold

Abdou Bousso, Ameth Ndiaye

This paper is devoted to the study of Ricci-Yamabe solitons on a particular class of Walker manifolds in dimension 3. We consider a Walker metric where the function f depends on th…

Ricci-Yamabe Soliton on a Class of -Dimensional Walker Manifolds

Abdou Bousso, Ameth Ndiaye

This article explores Ricci-Yamabe solitons on a specific class of 4-dimensional Walker manifolds. Walker manifolds, characterized by the existence of a parallel null distribution,…
