Arithmetic subgroups of Chevalley group schemes over function fields I: quotients of the Bruhat-Tits building by ${P}$ -arithmetic subgroups

Claudio Bravo, Benoit Loisel

Let $G$ be a reductive Chevalley group scheme (defined over $Z$ ). Let $C$ be a smooth, projective, geometrically integral curve over a field $\mathbb{F}…

Quotients of the Bruhat-Tits tree by function field analogs of the Hecke congruence subgroups

Claudio Bravo

Let C be a smooth, projective and geometrically integral curve defined over a finite field F. For each closed point P of C, let R be the ring of functions that are regular outside…
