Yet another characterization of Birkhoff Billiards inside discs
Klaudiusz Czudek, Jacopo De Simoi, Andrew Gad +1
In this short paper, we show a characterization of Birkhoff Billiards inside discs which is related to the expansion of the formal Lazutkin conjugacy at the boundary.

Statistical properties of mostly expanding fast-slow partially hyperbolic systems
Jacopo De Simoi, Kasun Fernando, Nicholas Fleming-Vázquez
We consider a class of fast-slow partially hyperbolic systems on given by -perturbations of maps where are exp…

Marked length spectrum rigidity for Anosov magnetic surfaces
Valerio Assenza, Jacopo de Simoi, James Marshall Reber +1
We show that if is a closed, connected, oriented surface, and two Anosov magnetic systems on are conjugate by a volume-preserving conjugacy isotopic to the identity, with t…
