Geodesic Rosen continued fractions

Number Theory 2015-04-22 v2 Combinatorics

Abstract

We describe how to represent Rosen continued fractions by paths in a class of graphs that arise naturally in hyperbolic geometry. This representation gives insight into Rosen's original work about words in Hecke groups, and it also helps us to identify Rosen continued fraction expansions of shortest length.
