Abstract

We prove that the bijective correspondence between the space of bounded measured laminations MLb(H)ML_b(\mathbb{H}) and the universal Teichm\"uller space T(H)T(\mathbb{H}) given by λEλS1\lambda\mapsto E^{\lambda}|_{S^1} is a homeomorphism for the Fr\'echet topology on MLb(H)ML_b(\mathbb{H}) and the Teichm\"uller topology on T(H)T(\mathbb{H}), where EλE^{\lambda} is an earthquake with earthquake measure λ\lambda. A corollary is that earthquakes with discrete earthquake measures are dense in T(H)T(\mathbb{H}). We also establish infinitesimal versions of the above results.
