Classifying spaces with virtually cyclic stabilizers for linear groups

Dieter Degrijse, Ralf Köhl, Nansen Petrosyan

We show that every discrete subgroup of admits a finite dimensional classifying space with virtually cyclic stabilizers. Applying our methods to $\mathr…

Quotients of trees for arithmetic subgroups of PGL2 over a rational function field

Ralf Köhl, Bernhard Mühlherr, Koen Struyve

In this note we compute the fundamental domain of the action on the corresponding Bruhat-Tits tree of the arithmetic subgroup of PGL2 with respect to an arbitrary place of the rati…
