Entropy and Translation Length in the Ray Graph

Juliette Bavard, Danny Calegari, Alden Walker

Let $Γ$ be the mapping class group of the plane minus a Cantor set, acting on the ray graph $R$ , and for $γ \in Γ$ let $τ (γ)$ denote the translation length of $γ$ on $\mat…

Laminations and External Angles for Similarity Pairs

Danny Calegari, Alden Walker

A {\em similarity pair} is the dynamical system in $C$ generated by two maps $f : z \to sz - 1$ and $g : z \to sz + 1$ for $∣ s ∣ < 1$ . Associated to the dynamical system is an attrac…

Quasimorphisms and Pseudo-Anosov flows

Danny Calegari, Jonathan Zung

We describe two connections between the theory of quasimorphisms and pseudo-Anosov flows without perfect fits on closed hyperbolic 3-manifolds. First we show that for every such fl…
