An introduction to enumerative geometry

Yun Shi (UIUC Math)

Abstract: One important question in enumerative geometry concerns how many curves there are on a Calabi-Yau 3-fold. In this talk, I will present one of the approaches to the classical problem: there are 27 lines on a smooth cubic surface. Motivated by this approach, we will discuss the modern set-up to answer the curve counting questions, in particular its applications to Donaldson-Thomas theory.
