Let C be a complex projective curve and let L and M be two line bundles on C. One can associate with L and M some natural maps, which are called Gaussian maps, between spaces of global sections of certain sheaves on C. 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.
