Shears for quasisymmetric maps

Dragomir Šarić

We give an elementary proof of a theorem that characterizes quasisymmetric maps of the unit circle in terms of shear coordinates on the Farey tesselation. The proof only uses the n…

Train tracks and measured laminations on infinite surfaces

Dragomir Šarić

Let $X$ be an infinite Riemann surface equipped with its conformal hyperbolic metric such that the action of the covering group $π_{1} (X)$ on $X ~$ is of the first kind-i.e., t…

Convergence of Teichmüller deformations in the universal Teichmüller space

Hideki Miyachi, Dragomir Šarić

Let $φ : D \to C$ be an integrable holomorphic function on the unit disk $D$ and $D_{φ} : D \to T (D)$ the Teichmüller disk in the universal Teic…

Fenchel-Nielsen coordinates on upper bounded pants decompositions

Dragomir Šarić

Let $X_{0}$ be an infinite genus hyperbolic surface (whose boundary components, if any, are closed geodesics or punctures) which has an upper bounded pants decomposition. The length…
