Title: What does it take to solve a difference equation?
Abstract: Linear $q$-difference equations, such as the quantum Knizhnik-Zamolodchikov equation, appear in diverse problems of mathematical physics, from 2-dimensional lattice models to supersymmetric gauge theories in 2+1 dimensions. Over the years, many strategies for studying their solutions have been developed, but perhaps none is currently as efficient as what comes out of the enumerative geometry interpretation. It takes several geometric ideas to produce a good formula, and my goal in the talk is to give an overview of these ideas aimed at nonspecialists.
