Singularities of theta divisors and the Tannakian Schottky problem
Constantin Podelski
With the Tannakian formalism, one can attach to any principally polarized abelian variety a reductive group, along with a representation. We obtain a completely new characterizatio…
The boundary of the bielliptic Prym locus
Constantin Podelski
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…
The Gauss map for bielliptic Prym varieties
Constantin Podelski
We completely describe the degree of the Gauss map of the theta divisor of bielliptic Prym varieties. We characterize bielliptic Prym varieties whose Gauss degree is the same as Ja…
The Gauss Map on Theta Divisors with Transversal Singularities
Constantin Podelski
We use Lagrangian specialization to compute the degree of the Gauss map on Theta divisors with transversal singularities. This computes the Gauss degree for a genera…
