Uniform hyperbolicity of the curve graph via surgery sequences

Geometric Topology 2015-05-27 v1

Abstract

We prove that the curve graph \calC(1)(S)\calC^{(1)}(S) is Gromov-hyperbolic with a constant of hyperbolicity independent of the surface SS. The proof is based on the proof of hyperbolicity of the free splitting complex by Handel and Mosher, as interpreted by Hilion and Horbez.
