Bendings by finitely additive transverse cocycles

Abstract

Let $S$ be any closed hyperbolic surface and let $\lambda$ be a maximal geodesic lamination on $S$. The amount of bending of an abstract pleated surface (homeomorphic to $S$) with the pleating locus $\lambda$ is completely determined by an $(\mathbb{R}/2\pi \mathbb{Z})$-valued finitely additive transverse cocycle $\beta$ to the geodesic lamination $\lambda$. We give a sufficient condition on $\beta$ such that the corresponding pleating map ${\tilde{f}}_{\beta }:{\mathbb{H}}^2\to {\mathbb{H}}^3$ induces a quasiFuchsian representation of the surface group ${\pi }_1(S)$. Our condition is genus independent.
