MIT Symplectic Seminar

Thu May 9, 2024 3:30–4:30 PM

Location

Building 2, 449

Description

Speaker: Shira Tanny (Institute for Advanced Study)Title: From Gromov–Witten theory to the closing lemma.Abstract: An old question of Poincaré concerns creating periodic orbits via perturbations of a flow/diffeomorphism. While pseudoholomorphic methods have successfully addressed this question in dimensions 2-3, the higher-dimensional case remains less understood. I will describe a connection between this question and Gromov–Witten invariants, which goes through a new class of invariants of symplectic cobordisms. This is a joint work with Julian Chaidez.
