Reduction theory for Fuchsian groups with cusps

Adam Abrams, Svetlana Katok, Ilie Ugarcovici

We study a family of Bowen-Series-like maps associated to any finitely generated Fuchsian group of the first kind with at least one cusp. These maps act on the boundary of the hype…

On the topological entropy of (a,b)-continued fraction transformations

Adam Abrams, Svetlana Katok, Ilie Ugarcovici

We study the topological entropy of a two-parameter family of maps related to (a,b)-continued fraction algorithms and prove that it is constant on a square within the parameter spa…

Rigidity and flexibility of entropies of boundary maps associated to Fuchsian groups

Adam Abrams, Svetlana Katok, Ilie Ugarcovici

Given a closed, orientable surface of constant negative curvature and genus , we study the topological entropy and measure-theoretic entropy (with respect to a smooth inva…

Rigidity of topological entropy of boundary maps associated to Fuchsian groups

Adam Abrams, Svetlana Katok, Ilie Ugarcovici

Given a closed, orientable surface of constant negative curvature and genus , we study a family of generalized Bowen-Series boundary maps and prove the following rigidity…

Flexibility of measure-theoretic entropy of boundary maps associated to Fuchsian groups

Adam Abrams, Svetlana Katok, Ilie Ugarcovici

Given a closed, oriented, compact surface of constant negative curvature and genus , we study the measure-theoretic entropy of the Bowen-Series boundary map with respe…

Adler and Flatto revisited: cross-sections for geodesic flow on compact surfaces of constant negative curvature

Adam Abrams, Svetlana Katok

We describe a family of arithmetic cross-sections for geodesic flow on compact surfaces of constant negative curvature based on the study of generalized Bowen-Series boundary maps…
