ABSTRACT
We introduce some tools of symbolic dynamics to study the hyperbolic directions of partially hyperbolic diffeomorphisms, emulating the well-known methods available for uniformly hyperbolic systems.
Acknowledgments
The results presented in this article are generalizations of the ones obtained in my MSc project under the supervision of Mike Shub. I am very grateful to him for all the ideas and encouragement that he gave me. I have also benefited a lot from conversations wit Charles Pugh, Enrique Pujals and Federico Rodriguez-Hertz. The author is particularly indebted to the referee for her/his diligent work, that allowed to remove errors and greatly improved the correctness and readability of the article.
To all of them, my most sincere thanks.

Notes
1. In the literature, the notion of pseudo-group is usually defined using open sets instead of proper ones, but the extension to the later case is straightforward. Compare [Citation10].
2. A foliated atlas {U} k is nice if whenever there exists a distinguished open set containing .
