On optimal -adic uniformization of unitary Shimura curves

arXiv:2605.19443

Abstract

The paper is a continuation of the paper of Kudla-Rapoport-Zink on -adic uniformization of Shimura curves associated to a group of binary unitary similitudes. Here we consider two variants: first, the RSZ variant, for which we can allow any level which is maximal at the chosen special -adic place where the group is anisotropic; second, the unitary group variant. The latter is based on an explicit determination of the integral local Shimura variety associated to an anisotropic unitary group over a -adic local field.
