In the late 1970’s, Thurston dramatically changed the nature of 3-manifold theory with the introduction of his Geometrisation Conjecture, and by proving it in the case of Haken 3-manifolds [23]. The conjecture for general closed orientable 3-manifolds remains perhaps the most important unsolved problem in the subject. A weaker form of the conjecture [19] deals with the fundamental group of a closed orientable 3-manifold. It proposes that either it contains Z ⊕ Z as a subgroup or it is word…

When M is the exterior of the figure-eight knot, the number of exceptional slopes is 10, and this was conjectured by Gordon in [19] to be an upper bound that holds for all M .

We study random elements of subgroups (and cosets) of the mapping class group of a closed hyperbolic surface, in part through the properties of their mapping tori. In particular, we study the…
