Abstract
We study the ramified Prym map [Formula: see text] which assigns to a ramified double cover of a smooth irreducible curve of genus [Formula: see text] ramified in [Formula: see text] points the Prym variety of the covering. 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 [Formula: see text].
