Denis Nesterov (University of Vienna) “Enumerative mirror symmetry for moduli spaces of Higgs bundles”
–
In the third talk, we discuss how quasimaps can be used to translate S-duality of Vafa-Witten invariants of Curve x Curve’ to a duality of quasimap invariants of moduli spaces of Higgs bundles on Curve. This provides an enumerative realization of Kapustin-Witten’s dimensional reduction in the case of SL and PGL.
