## The abelian/nonabelian correspondence in Gromov-Witten theory II

Topic:

Given a "good" action of a reductive complex algebraic group G on a

projective manifold X, the abelian/nonabelian correspondence refers to

a precise relation that exists between topological invariants

(cohomology, K-theory) of the Geometric Invariant Theory quotients X//G

and X//T, where T is a maximal abelian subgroup in G. In this series of

talks, we will explain how to extend this relation to the (genus zero)

Gromov-Witten theories of the two quotients, based on joint works with

Aaron Bertram and Claude Sabbah.
