#### Integrable billiards and symplectic embedding problems

###### Daniele Sepe (Universidade Federal Fluminense, Brazil)

Abstract: A driving question in symplectic topology is to determine whether one symplectic manifold embeds symplectically into another of equal dimension. In this talk, we shall consider a family of symplectic manifolds, called Lagrangian products, that have come to the fore in recent years because of their connection with billiards through the work of Artstein-Avidan, Karasev and Ostrover. We shall illustrate some recent results concerning embeddings of sufficiently symmetric Lagrangian products in any dimension. The proof relies on integrable billiards and is inspired by an idea of Ramos. Time permitting, we shall discuss some ongoing developments and open questions. This is joint work with V. G. B. Ramos.
