Pragmatic finiteness properties of locally compact groups
Dorian Chanfi, Stefan Witzel
We compare finiteness properties of locally compact groups that generalize the properties of being compactly generated and of being compactly presented. Three such families of prop…

Polyhedral compactifications of Bruhat-Tits buildings of quasi-reductive groups
Dorian Chanfi
Given a quasi-reductive group over a local field , using Berkovich geometry, we exhibit a family of -equivariant compactifications of the Bruhat-Tits building $\mathca…

Wonderful compactifications of Bruhat-Tits buildings in the non-split case
Dorian Chanfi
Given an adjoint semisimple group over a local field , we prove that the maximal Satake-Berkovich compactification of the Bruhat-Tits building of can be identified with…
