Department of Mathematics - Algebra and Geometry Seminar - Wall-crossing formula I: Stable quasimaps and their wall-crossing formula

In this lecture, we will introduce the notion of quasimaps and their stability conditions. We will establish the essential geometric properties of the moduli of epsilon-stable quasimaps. After defining the small I-function using quasimap graph space, we will introduce the quasi-map wall-crossing formula and explain its geometric meaning.
