Speaker: Joé Brendel (Neuchâtel) Title: Product tori in S²×S² and Lagrangian packing

Abstract: A product torus in S²×S² is a Lagrangian torus obtained as the product of circles in the factors. The goal of this talk is to give a classification up to symplectomorphisms of such tori and illustrate that interesting things happen in case the symplectic form is non-monotone. Among other applications, we will answer a question about Lagrangian packings posed by Polterovich--Shelukhin. This is partially based on joint work with Joontae Kim.
