Enumerative mirror symmetry for moduli spaces of Higgs bundles and S-duality

Abstract

We derive conjectures, called genus 1 Enumerative mirror symmetry for moduli spaces of Higgs bundles, which relate curve-counting invariants of moduli spaces of Higgs ${\mathrm{SL}}_r$-bundles to curve-counting invariants of moduli spaces of Higgs ${\mathrm{PGL}}_r$-bundles. This contrasts with Enumerative mirror symmetry for Calabi-Yau 3-folds which relates curve-counting invariants to periods. We also provide extensive mathematical evidence for these conjectures. The conjectures are obtained with the help of the theory of quasimaps to moduli spaces of sheaves, Tanaka-Thomas's construction of Vafa-Witten theory, Jiang-Kool's enumerative S-duality of Vafa-Witten invariants and Manschot-Moore's calculations. We use the latter together with some basic computations to give a complete list of conjectural expressions for genus 1 quasimap invariants for all prime ranks. They have many interesting properties, among which is quantum $\chi$-independence. The wall-crossing to Gromov-Witten theory is also thoroughly discussed.
