When is a polarised abelian variety determined by its $p$ -divisible group?

Tomoyoshi Ibukiyama, Valentijn Karemaker, Chia-Fu Yu

We study the Siegel modular variety $A_{g} \otimes F_{p}$ of genus $g$ and its supersingular locus $S_{g}$ . As our main result we determine precis…

Arithmetic Satake compactifications and algebraic Drinfeld modular forms

Urs Hartl, Chia-Fu Yu

In this article we construct the arithmetic Satake compactification of the Drinfeld moduli schemes of arbitrary rank over the ring of integers of any global function field away fro…
