On the Teichm{ü}ller space of acute triangles

Hideki Miyachi, Ken'Ichi Ohshika, Athanase Papadopoulos

We continue the study of the analogue of Thurston's metric on the Teichm{ü}ller space of Euclidean triangle which was started by Saglam and Papadopoulos in [1].By direct calculatio…

Thurston's broken windows only theorem revisited

Ken'ichi Ohshika

The'broken windows only theorem' is the main theorem of the third paper among a series of the paper in which Thurston proved his uniformisation theorem for Haken manifolds. In this…

The Teichm{ü}ller-Randers metric

Hideki Miyachi, Ken'Ichi Ohshika, Athanase Papadopoulos

In this paper, we introduce a new asymmetric weak metric on the Teichm{ü}ller space of a closed orientable surface with (possibly empty) punctures.This new metric, which we call th…

Thurston's Bounded image theorem

Cyril Lecuire, Ken'ichi Ohshika

Thurston's bounded image theorem is one of the key steps in his proof of the uniformisation theorem for Haken manifolds. Thurston never published its proof, and no proof has been k…

The infinitesimal and global Thurston geometry of Teichm{ü}ller space

Yi Huang, Ken'Ichi Ohshika, Athanase Papadopoulos

We undertake a systematic study of the infinitesimal geometry of the Thurston metric, showing that the topology, convex geometry and metric geometry of the tangent and cotangent sp…

Realisation of bending measured laminations by Kleinian surface groups

Shinpei Baba, Ken'ichi Ohshika

For geometrically finite Kleinian surface groups, Bonahon and Otal proved the existence part, and partly the uniqueness part of the bending lamination conjecture. In this paper, we…
