Stability of the chemostat system with a mutation factor
Terence Bayen, Henri Cazenave-Lacroutz, Jerome Coville
In this paper, we consider a resource-consumer model taking into account a mutation effect between species (with constant mutation rate). The corresponding mutation operator is a d…
Rigidity in topology C^0 of the Poisson bracket for Tonelli Hamiltonians
M. -C Arnaud
We prove the following rigidity result for the Tonelli Hamiltonians. Let T * M be the cotangent bundle of a closed manifold M endowed with its usual symplectic form. Let (F\_n) be…
The non-hyperbolicity of irrational invariant curves for twist maps and all that follows
M. -C Arnaud, P Berger
The key result of this article is key lemma: if a Jordan curve is invariant by a given C 1+ -diffeomorphism f of a surface and if carries an ergodic hyperbolic probabili…
Boundaries of instability zones for symplectic twist maps
Marie-Claude Arnaud
We construct a symplectic twist map f of the annulus that has an essential invariant curve C such that: - C is not differentiable; - the dynamics of f restricted to C is conj…
