Abstract

Let $\mathbb{A}^n_k$ be the affine space. Consider the $n$ divisors given by the usual hyperplanes. Suppose we are given Bruhat-Tits group schemes at the local ring of each of these divisors. We show the existence of a global group scheme on the affine space that recovers these all after restriction. This is joint work with Professor Vikraman Balaji of CMI.
