Le prochain séminaire Nantes-Orsay de géométrie de contact et symplectique aura lieu le vendredi 19 octobre 2018 à Nantes.
Au programme en salle Eole :
14h00-15h00 Egor Shelukhin (Montréal)
Titre: On the Lagrangian spectral norm and barcodes
Réumé: We discuss upper and lower bounds on the spectral norm in Lagrangian Floer theory, their implications for the associated barcodes, and additional applications. This talk is partially based on joint work with Asaf Kislev.
15h30-16h30 Jaime Bustillo (ENS Paris)
Titre: A coisotropic non-squeezing theorem in symplectic geometry.
Résumé : I will explain how generating functions and Viterbo's capacities can be used to prove a coisotropic non-squeezing theorem for Hamiltonian diffeomorphisms of R^{2n} generated by sub-quadratic Hamiltonians H. We will then see the relation of this theorem with the middle dimensional symplectic rigidity problem. If I have time, I will briefly explain how this type of rigidity appears in the context of Hamiltonian PDEs or $C^0$ symplectic geometry.
