On the non-Transversality of the Hyperelliptic Locus and the Supersingular Locus for
Andreas Pieper
This paper gives a criterion for a moduli point to be a point of non-transversal intersection of the hyperelliptic locus and the supersingular locus in the Siegel moduli stack $\ma…
Theta Nullvalues of Supersingular Abelian varieties
Andreas Pieper
Let be a polarization with connected kernel on a superspecial abelian variety . We give a sufficient criterion which allows the computation of the theta nullvalues of any…
Constructing all Genus 2 Curves with Supersingular Jacobian
Andreas Pieper
L. Moret-Bailly constructed families of genus 2 curves with supersingular jacobian. In this paper we first classify the reducible fibers of a…
A Global Crystalline Period Map
Michael Neaton, Andreas Pieper, Catherine Ray
The crystalline period map is a tool for linearizing -divisible groups. It has been applied to study the Langlands correspondences, and has possible applications to the homotopy…
