Geometric Control and Dynamics

Participants : Ayadi Lazrag, Ludovic Rifford, Rafael Ruggiero [PUC-RIO] .

Following [77], [57] and [58], we apply techniques from geometric control to the study of perturbations of Hamiltonian flows. In [9], we prove a uniform Franks' lemma at second order for geodesic flows and apply the result in persistence theory.
