## Abstract

Let F be a global field, let S be a nonempty finite set ofplaces of F which contains the archimedean places of F, let d ≥ 1, and let X =_{v} _{∈S} X_{v} where X_{v} is the symmetric space (resp., Bruhat-Tits building) associated to PGL_{d} (F_{v}) if v is archimedean (resp., non-archimedean). In this paper, we construct compactifications Γ\ ¯X of the quotient spaces Γ\X for S-arithmetic subgroups Γ of PGL_{d} (F). The constructions make delicate use of the maximal Satake compactification of X_{v} (resp., the polyhedral compactification of X_{v} of Gérardin and Landvogt) for v archimedean (resp., non-archimedean). We also consider a variant of ¯X in which we use the standard Satake compactification of X_{v} (resp., the compactification of X_{v} due to Werner).
