Ionut Ciocan-Fontanine: Stable quasimaps and GW theory of GIT quotients
I will discuss certain new compactifications with good properties of moduli spaces of maps from nonsingular marked curves to a class of GIT quotients, generalizing from a unified perspective many particular examples considered earlier in the literature. I will then present some applications to Gromov-Witten theory. The talk is based on joint works with Bumsig Kim and Davesh Maulik.
