The boundary of the bielliptic Prym locus

Algebraic Geometry 2023-12-29 v1

Abstract

We study the conormal geometry theta divisors of certain singular bielliptic curves. We apply these results to the boundary components \mathscr{S}_\underline{d} of the bielliptic Prym locus. We obtain results on the Gauss map, compute the Chern-Mather class and the characteristic cycle of the intersection complex of the corresponding Prym theta divisor.
