$θ$ -almost twisted Poisson cohomology

Nasser Saipele Nansidi, Bertuel Tangue Ndawa, Joseph Dongho

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

$C^{1}$ -Diffeomorphism Class of some Circle Maps with a Flat Interval

Bertuel Tangue Ndawa, Carlos Ogouyandjou

We study a certain class circle maps which are constant on one interval (called flat piece), and such that the degrees of the singularities at the boundary of the flat piece are di…

Cherry Maps with Different Critical Exponents: Bifurcation of Geometry

Bertuel Tangue Ndawa

We consider order preserving $C^{3}$ circle maps with a flat piece, irrational rotation number and critical exponents $(ℓ_{1}, ℓ_{2})$ . We detect a change in the geometry of the sy…
