Title

Quasimap invariants and mirror maps

Abstract

The moduli spaces of stable quasimaps unify various moduli appearing in the study of Gromov-Witten Theory. We introduce big I-functions as the quasimap version of J-functions, generalizing Givental’s small I-functions of smooth toric complete intersections. The J-functions are the GW counterparts of periods of mirror families. We discuss some advantages of I-functions, in particular an explanation of mirror maps. This is joint work with I. Ciocan-Fontanine. If time permitted, I will also report on the stable quasimaps for orbifold targets and I-functions of toric orbifolds. This is joint work with I. Ciocan-Fontanine and D. Cheong.
