Séminaire CIRGET: «Foliations, contact structures and Anosov flows in dimension 3»

Conférencier:Federico Salmoiraghi (Queen's)

Anosov flows are an important class of dynamical systems due to their ergodic and geometric properties. Even though they represent examples of chaotic dynamics, they enjoy the remarkable property of being stable under small perturbations. In this talk, I will explain how, perhaps surprisingly, Anosov flows are related to both integrable plane fields (foliations) and totally non-integrable plane fields (contact structures). The latter represents a less-studied approach that has the potential to make new connections to other branches of mathematics, such as symplectic geometry and Hamiltonian dynamics. Along the way, I will discuss some applications and examples with particular emphasis on the theory of surgery of Anosov flows.
