Title: Flow polytopes and gentle algebras

Abstract: Flow polytopes model the space of unit flows on directed acyclic graphs. They appear in many areas of mathematics including optimization, toric geometry, diagonal harmonics, and representation theory.  Furthermore, many important families of polytopes are examples of flow polytopes including associahedra, generalized permutohedra, Gelfand-Tsetlin polytopes, and certain order polytopes.  In this talk, we will discuss an interesting new connection between combinatorics of flow polytopes and representation theory of gentle algebras.  In particular, DKK triangulations of flow polytopes correspond to tau-tilting posets of the associated gentle algebras.

Title: Homological mirror symmetry via tensor-triangular geometry

Abstract: Homological mirror symmetry (HMS) conjectures an equivalence between the Fukaya category of a symplectic manifold and the derived category of coherent sheaves on its mirror scheme. We discuss a tensor-triangular geometric approach to HMS. In particular, we present a necessary and sufficient condition for a Fukaya category to be equivalent to the perfect derived category of a Noetherian scheme. This perspective also provides a method for constructing a mirror scheme from purely Fukaya-categorical data and leads to a natural construction of an A∞-functor.
