We focus on the six cases where the dimension of the source is strictly greater than the dimension of the target giving a geometric description of the generic fiber. We also give an explicit example of a totally geodesic curve which is an irreducible component of a fiber of the Prym map $\mathscr{P}_{1,2}$.application/pdfeng(c) World Scientific Publishing, 2021Corbes algebraiquesGeometria algebraicaAlgebraic curvesAlgebraic geometryinfo:eu-repo/semantics/article7069022023-01-05info:eu-repo/semantics/openAccess
