"Rank-2 odd degree moduli spaces of co-Higgs bundles"

This talk will be a continuation of my previous talk, we are going to show how the smooth moduli space of rank-2, odd-degree co-Higgs bundles can be interpreted as a kind of universal elliptic curve.

Gromov-Witten invariants play an essential role in mirror symmetry and enumerative geometry. Despite this, there are few effective tools for computing Gromov-Witten invariants of blow-ups. Blow-ups of X can be rewritten as subvarieties of Grassmann bundles over X. In joint work with Tom Coates and Wendelin Lutz, we exploit this fact and extend the abelian/non-abelian correspondence, a modern tool in Gromov-Witten theory. Combining these two steps allows us to get at the genus 0 invariants of a large class of blow-ups.
