Factorization of Isomorphisms of $(H, θ)$ -twisted Lie algebroids: Gauge Transformations, Conformal Casimir Transformations, and de Rham Obstruction

Nasser Saipele nansidi, Bertuel Tangue Ndawa, Luc Emery Diekouam Fotso +2

We study the isomorphism groupoid $T (M)$ of $θ$ -almost twisted Poisson ( $θ$ -atP) structures on a smooth manifold $M$ , focusing on the internal structure of its morphisms.…

Generic three-parameter unfolding of a completely degenerate germ of a vector field on $R^{3}$

Samuel Diangitukulu Ndimba, Aimable Sayinzoga, Bertuel Tangue Ndawa +2

In this work, we analyze a completely degenerate germ of a real vector field at the origin of $R^{3}$ . We construct a generic three-parameter unfolding of this germ and iden…

Lifting Symplectomorphism Group Actions on Bi-Lagrangian Structures to the Whitney Sum

Bertuel Tangue Ndawa, Ferdinand Ngakeu, Nasser Saipele Nansidi

Let $M$ be a manifold endowed with a bi-Lagrangian structure $(I ¨ , F_{1}, F_{2})$ . Thus, $I ¨ $ is a symplectic form, and $(F_{1}, F_{2})$ is a pair o…

On the geometric quantization of $I^¸$ -almost twisted Poisson manifold

Nasser Saipele Nansidi, Bertuel Tangue Ndawa, Joseph Dongho

We introduce and investigate the concept of a $I^¸$ -almost twisted Poisson manifold $(M, I^, I ¨ , I^¸)$ . This structure consists of a smooth manifold $M$ equipped with a bivector field $…

$I^¸$ -almost twisted Poisson cohomology

Nasser Saipele Nansidi, Bertuel Tangue Ndawa, Joseph Dongho

We introduce the notion of a $I^¸$ -almost twisted Poisson structure on manifolds, which involves incorporating a closed $1$ -form $I^¸$ into twisted Poisson structures under specific…

Dynamics on Bi-Lagrangian Structures and Cherry maps

Bertuel Tangue Ndawa

We consider a bi-Lagrangian structure $(ω, F_{1}, F_{2})$ on a manifold $M$ ; that is, $(M, ω, F_{1}, F_{2})$ is a bi-Lagrangian manifold. We prolong bi-L…
