Foliations and ergodicity of transverse measures

This master's thesis is a study of the article "Unique ergodicity for horocycle foliations", by Rufus Bowen and Brian Marcus. The objective is to present the construction of invariant measures of the stable and unstable foliations of basic sets of Axiom A diffeomorphism. We show that these measures are unique in a certain sense, and for that we make use of a conjugacy to a symbolic space and a shift dynamics to translate the problem to something more manageable. The conjugacy exists thanks to the existence of Markov partitions (AU)
