Piecewise rotations: symbolic dynamics
Résumé
We consider the piecewise rotation studied in \cite{Bosh.Goet.03}, \cite{Goet.Quas.09} and \cite{Che.Goe.Qua.12}. If the angle belongs to the set $\{\pi/2,\pi/3,\pi/6,\pi/4,\pi/5\}$ we give a complete description of the symbolic dynamics of this map whatever the map is bijective, non injective or non surjective.
