Topological mirror symmetry for rank two character varieties of surface groups

Topological mirror symmetry for rank two character varieties of surface groups

The moduli spaces of flat SL 2 - and PGL 2 -connections are known to be singular SYZ-mirror partners. We establish the equality of Hodge numbers of their intersection (stringy) cohomology. In rank two, this answers a question raised by Tamás Hausel in Remark 3.30 of “Global topology of the Hitchin s...

Zusammenfassung:The moduli spaces of flat SL 2 - and PGL 2 -connections are known to be singular SYZ-mirror partners. We establish the equality of Hodge numbers of their intersection (stringy) cohomology. In rank two, this answers a question raised by Tamás Hausel in Remark 3.30 of “Global topology of the Hitchin system”.
