Unique Ergodicity For Infinite Area Translation Surfaces
Alba Málaga Sabogal, Serge Troubetzkoy
We consider infinite staircase translation surfaces with varying step sizes. For typical step sizes we show that the translation flow is uniquely ergodic in almost every direction.…

Minimality of the Ehrenfest wind-tree model
Alba Málaga Sabogal, Serge Troubetzkoy
We consider aperiodic wind-tree models, and show that for a generic (in the sense of Baire) configuration the wind-tree dynamics is minimal in almost all directions, and has a dens…
