Abstract |
|
We show that every atoroidal endperiodic map of an infinite-type surface can be obtained from a depth-one foliation in a fibered hyperbolic 3-manifold, reversing a well-known construction of Thurston. This can be done almost-transversely to the canonical suspension flow, and as a consequence we recover the Handel–Miller laminations of such a map directly from the fibered structure. We also generalize from the finite-genus case the relation between topological entropy, growth rates of periodic points, and growth rates of intersection numbers of curves. Fixing the manifold and varying the depth-one foliations, we obtain a description of the Cantwell–Conlon foliation cones and a proof that the entropy function on these cones is continuous and convex. |
