Equidistribution of cusp points of Hecke triangle groups
Laura Breitkopf, Marc Kesseböhmer, Anke Pohl
In the framework of infinite ergodic theory, we derive equidistribution results for suitable weighted sequences of cusp points of Hecke triangle groups encoded by group elements of…

Amount of failure of upper-semicontinuity of entropy in noncompact rank one situations, and Hausdorff dimension
Shirali Kadyrov, Anke D. Pohl
Recently, Einsiedler and the authors provided a bound in terms of escape of mass for the amount by which upper-semicontinuity for metric entropy fails for diagonal flows on homogen…
