The geometry of triples of antipodal ideal chambers of affine buildings

Corina Ciobotaru, Corentin Le Bars

In this article, we investigate two notions of genericity for triples of antipodal ideal chambers in a locally finite affine building $X$ : one defined at the ideal boundary $X^{\in…

Covers of Bruhat-Tits trees

Corina Ciobotaru, Peter Vang Uttenthal

Let $G$ be a locally compact group and let $G$ be a central extension that splits over a maximal compact subgroup $K$ of $G$ . We derive an explicit cocycle that lifts t…

Dynamical boundaries of affine buildings: C*-simplicity and Poisson boundaries

Corina Ciobotaru, Corentin Le Bars

We investigate a class of groups acting on possibly exotic affine buildings $X$ and possessing good proximal properties. Such groups are termed of general type, and their dynamics…

Chabauty limits of fixed point groups of $p$ -adic involutions

Corina Ciobotaru

We study Chabauty limits of the fixed-point group of $k$ -points $H_{k}$ associated with an involutive $k$ -automorphism $I^¸$ of a connected linear reductive group $G$ defined over a n…
