On the locus of Prym curves where the Prym--canonical map is not an embedding
Abstract
We prove that the locus of Prym curves (C,η) of genus g ≥ 5 for which the Prym-canonical system |ωC(η)| is base point free but the Prym--canonical map is not an embedding is irreducible and unirational of dimension 2g+1.
