The main result is that this is a \u2018perfect' functional provided due account is taken of its gauge symmetry. This enables topological conclusions to be drawn about the critical sets and leads eventually to information about the moduli space of algebraic bundles over the Riemann surface. This in turn depends on the interplay between the holomorphic and unitary structures, which is analysed in detail.<\/jats:p>","DOI":"10.1098\/rsta.1983.0017","type":"journal-article","created":{"date-parts":[[2006,12,18]],"date-time":"2006-12-18T18:37:32Z","timestamp":1166467052000},"page":"523-615","source":"Crossref","is-referenced-by-count":906,"title":["The Yang-Mills equations over Riemann surfaces"],"prefix":"10.1098","volume":"308","author":[{"given":"Michael Francis","family":"Atiyah","sequence":"first","affiliation":[{"name":"Mathematical Institute, University of Oxford, 24-29 St Giles, Oxford OX1 3LB, U.
