摘要:  I will give a survey of results on the topology of moduli spaces of Higgs bundles over a compact Riemann surface. Much progress has been made by various people in computing the cohomology of the moduli space when the degree and rank of the bundle are coprime (and hence the moduli space is smooth), however the methods used do not apply when the moduli space is singular. The focus of the talk will be on recent joint work with George Daskalopoulos and Richard Wentworth in which we have developed new results on the cohomology of the moduli space in low rank that are also valid when the moduli space is singular.
