Résumé :
In linear dynamics, chaos requires the density of some orbits and the density of periodic points while frequent hypercyclicity assumes the existence of orbits visiting frequently each non-empty open set. These two notions that we thought were linked are not in general. However, neither are they completely foreign to each other and in particular when we consider the most studied operators in linear dynamics: weighted shifts.
