Aula Dal Passo, Dip. Matematica, Università "Tor Vergata", Roma
In this talk we will study the problem of prescribing Gaussian curvature on compact surfaces under conformal change of the metric with conical singularities. We restrict our attention to the case of the unit sphere and the case of sign-changing prescribed function, which presents some extra difficulties. Joint work with F. de Marchis (Sapienza università di Roma).
