Geodesic laminations and continued fractions
نویسنده
چکیده
We introduce the notion of “slope” for geodesic laminations. Slope is a positive irrational defined via regular continued fraction. The action of the mapping class group on lamination pulls back to the action of GL(2, Z) on real line. We discuss applications of slopes in complex analysis, low-dimensional topology, geometric group theory and C∗-algebras.

Geodesic laminations and Bratteli diagrams of AF C*-algebras
Geodesic laminations is a remarkable abstraction (due to W. P. Thurston) of many otherwise unrelated phenomena occurring in differential geometry, complex analysis and geometric topology. In this article we focus on connections of geodesic laminations with the inductive limits of finite-dimensional semi-simple C-algebras (AF C-algebras). Our main result is a bijection between combinatorial pres...

متن کاملCross Sections for Geodesic Flows and Α-continued Fractions
We adjust Arnoux’s coding, in terms of regular continued fractions, of the geodesic flow on the modular surface to give a cross section on which the return map is a double cover of the natural extension for the α-continued fractions, for each α ∈ (0, 1]. The argument applies in wide generality, as we illustrate with its application to the Rosen continued fractions and their recently introduced ...
متن کاملThe metric space of geodesic laminations on a surface II: small surfaces
We continue our investigation of the space of geodesic laminations on a surface, endowed with the Hausdorff topology. We determine the topology of this space for the once punctured torus and the 4–times punctured sphere. For these two surfaces, we also compute the Hausdorff dimension of the space of geodesic laminations, when it is endowed with the natural metric which, for small distances, is ...
متن کاملLinear structures on measured geodesic laminations
The space ML(F ) of measured geodesic laminations on a given compact closed hyperbolic surface F has a canonical linear structure arising in fact from different sources in 2-dimensional hyperbolic (eartquake theory) or complex projective (grafting) geometry as well in (2 + 1) Lorentzian one (globally hyperbolic spacetimes of constant curvature). We investigate this linear structure, by showing ...
