Flexibility of Lyapunov exponents with respect to two classes of measures on the torus

Alena Erchenko

We consider a smooth area-preserving Anosov diffeomorphism $f : T^{2} \to T^{2}$ homotopic to an Anosov automorphism $L$ of $T^{2}$ . It is known that t…

Geometry and entropies in a fixed conformal class on surfaces

Thomas Barthelmé, Alena Erchenko

We show the flexibility of the metric entropy and obtain additional restrictions on the topological entropy of geodesic flow on closed surfaces of negative Euler characteristic wit…
