Title: Tropical curve counting
Speaker: Sushmita Venugopalan (IMSc, Chennai)

Time: 3:30 pm
Venue: LH-1, Mathematics Department

Counting holomorphic curves in a symplectic manifold has been an area of research since Gromov’s work on this subject in the 1980s. Symplectic manifolds naturally allow a ‘cut’ operation. We explore what happens to curve count-based invariants when a collection of cuts is applied to a symplectic manifold. An interesting feature of curves in a multiply-cut manifold is that they have an underlying ‘tropical graph’, which is a graph that lives in the polytope associated to the cut.
