Title: Interpolation, q-difference equations, and curve counting
Abstract: There is an interesting topology behind such classical questions as interpolation and solving linear q-difference equations by integrals. It has to do with counting algebraic curves in some very specific geometries, which can be also phrased as computing indices in certain (2+1) dimensional supersymmetric QFTs. The talk will be an introduction to this circle of ideas.
