Simplicity of some twin tree automorphism groups with trivial commutation relations
Jun Morita, Bertrand Rémy
We prove simplicity for incomplete rank 2 Kac-Moody groups over algebraic closures of finite fields with trivial commutation relations between root groups corresponding to prenilpo…

Bruhat-Tits Theory from Berkovich's Point of View. I - Realizations and Compactifications of Buildings
Bertrand Rémy, Amaury Thuillier, Annette Werner
We investigate Bruhat-Tits buildings and their compactifications by means of Berkovich analytic geometry over complete non-Archimedean fields. For every reductive group G over a su…
