Let Sg,p denote the genus g orientable surface with p⩾0 punctures, and let ω(g,p)=3g+p−3>1 . We prove the existence of infinitely long geodesic rays (v0,v1,v2,…) in the curve graph satisfying the following optimal intersection property: for any natural numbers i and k , the endpoints vi,vi+k of any length k subsegment intersect at most fi,k(ω) times, where fi,k(x) is O(xk−2) . This answers a question of Dan Margalit.

Distance and intersection number in the curve graph of a surface

It is able to show that, in some special cases, the efficient geodesic algorithm can be used to build an algorithm that reduces $i(v,w)$ while preserving $d( v, w)$.

Quasi-morphisms on surface diffeomorphism groups

We show that the identity component of the group of diffeomorphisms of a closed oriented surface of positive genus admits many unbounded quasi-morphisms. As a corollary, we also deduce that this

Single-cylinder square-tiled surfaces and the ubiquity of ratio-optimising pseudo-Anosovs

In every connected component of every stratum of Abelian differentials, we construct square-tiled surfaces with one vertical and one horizontal cylinder. We show that for all but the hyperelliptic

Efficient geodesics and an effective algorithm for distance in the complex of curves

The method gives a new preferred finite set of geodesics between any two vertices of the complex of curves, called efficient geodesICS, which are different from the tight geodesic introduced by Masur and Minsky.

Pseudo-Anosovs optimizing the ratio of Teichm\"uller to curve graph translation length

A new construction of ratio optimizers is introduced and they are shown to be found arbitrarily deep into the Johnson filtration as well as in the point pushing subgroup.

Distance and intersection number in C ( S ) Birman , Morse , Wrinkle

We highlight a new relationship between the distance function d in the curve graph of a closed orientable surface S of genus g and the cellular decomposition of S induced by a filling pair of curves,



Uniform hyperbolicity of the graphs of curves

Let C.Sg;p/ denote the curve complex of the closed orientable surface of genus g with p punctures. Masur and Minksy and subsequently Bowditch showed that C.Sg;p/ is i–hyperbolic for some i D i.g;p/ .

Minimally intersecting filling pairs on surfaces

Let Sg denote the closed orientable surface of genus g . We construct exponentially many mapping class group orbits of pairs of simple closed curves which fill Sg and intersect minimally, by showing

Geometry of the mapping class groups III: Quasi-isometric rigidity

Let S be an oriented surface of finite type of genus g with m punctures and where 3g-3+m>1. We show that the mapping class group M(S) of S is quasi-isometrically rigid. We also give a different proof

Intersection numbers and the hyperbolicity of the curve complex

Abstract We give another proof of the result of Masur and Minsky that the complex of curves associated to a compact orientable surface is hyperbolic. Our proof is more combinatorial in nature and can


Thurston’s Ending Lamination Conjecture states that a hyperbolic 3manifold N with nitely generated fundamental group is uniquely determined by its topological type and its end invariants. In this

The classification of Kleinian surface groups I : Models and bounds : preprint

We give the first part of a proof of Thurston’s Ending Lamination conjecture. In this part we show how to construct from the end invariants of a Kleinian surface group a “Lipschitz model” for the

A Representation of Orientable Combinatorial 3-Manifolds

The following question has been posed by Bing [1]: "Which compact, connected 3-manifolds can be obtained from S3 as follows: Remove a finite collection of mutually exclusive (but perhaps knotted and

Geometry and rigidity of mapping class groups

We study the large scale geometry of mapping class groups MCG(S), using hyperbolicity properties of curve complexes. We show that any self quasi-isometry of MCG(S) (outside a few sporadic cases) is a

A short proof of the bounded geodesic image theorem

We give a combinatorial proof, using the hyperbolicity of the curve graphs, of the bounded geodesic image theorem of Masur and Minsky. Recently it has been shown that curve graphs are uniformly
