Semilinear automorphisms of reductive algebraic groups

Thierry Stulemeijer

Let $G$ be a connected reductive algebraic group over a field $k$ . We study the group of semilinear automorphisms Aut( $G \to$ Spec $k$ ) consisting of algebraic automorphisms of…

Borel density for approximate lattices

Michael Björklund, Tobias Hartnick, Thierry Stulemeijer

We extend classical density theorems of Borel and Dani--Shalom on lattices in semisimple, respectively solvable algebraic groups over local fields to approximate lattices. Our proo…

Chabauty limits of algebraic groups acting on trees

Thierry Stulemeijer

Given a locally finite leafless tree $T$ , various algebraic groups over local fields might appear as closed subgroups of $Aut (T)$ . We show that the set of closed cocompa…

Totally disconnected locally compact groups with a linear open subgroup

Pierre-Emmanuel Caprace, Thierry Stulemeijer

We describe the global structure of totally disconnected locally compact groups having a linear open compact subgroup. Among the applications, we show that if a non-discrete, compa…
