Holomorphic triples and the prescribed curvature problem on $S^2$ math.DG We prove new results on existence of solutions for the prescribed gaussian curvature problem on the euclidean sphere S^2. Those results are achieved by relating this problem with the holomorphic triples theory on Riemann surfaces. We think th...
