Abstract
The purpose of this paper is to generalize some recent results about Sturmian words and morphisms. This is done by introducing a new mathematical interpretation of them, using the modern topological framework of laminations and train tracks. The main result is a description of a class of languages invariant by the action of a finitely generated monoid of morphisms (where classical Sturmian objects represent the case over an alphabet of two letters). We also discuss how these languages can be effectively constructed, and we show how topological results about Pseudo-Anosov homeomorphisms can be proved in terms of D0L-systems theory.
