The work of Baranovsky, King-Newstead, Siebert-Tian and Zagier provided a complete set of relations between these classes, expressed in terms of a recursion in the genus. This paper accomplishes the same thing for the noncompact moduli spaces of Higgs bundles, in the sense of Hitchin and Simpson. There are many more independent relations than for stable bundles, but in a sense the answer is simpler, since the formulas are completely explicit, not recursive. The results of Kirwan on equivariant cohomology for holomorphic circle actions are of key importance.","lang":"eng"}],"_id":"1458","extern":1,"status":"public","type":"journal_article","publist_id":"5739","month":"04","volume":16,"acknowledgement":"The first author was supported by NSF grant DMS-97-29992.
