On the ergodicity of billiards in non-rational polygons
Apparaît également dans les collections : Dynamics and geometry in the Teichmüller space / Dynamique et géométrie dans l'espace de Teichmüller, ECM 2024 Invited Speakers
We will present a geometric criterion for the ergodicity of the billiard flow in a polygon with non-rational angles and discuss its application to the Diophantine case.
