Title: Gauss-Prym maps on Enriques surfaces. Abstract: Let C be a complex projective algebraic curve and let L and M be two line bundles on C. One can associate L and M with some natural maps between spaces of global sections of certain sheaves on C. These are called Gaussian-Wahl maps. These maps have been classically studied in connection with extendability questions of curves on surfaces. In this talk I will focus on the case of Enriques surfaces, presenting some natural questions that arise in this situation.
