Abstract

In this paper, we prove that given two foliations and on which are transverse, there exists a non-null homotopic loop in such that for every , and .

As a direct consequence, we get a general process for building new partially hyperbolic diffeomorphisms on closed -manifolds. [4] built a new example of dynamically coherent non-transitive partially hyperbolic diffeomorphism on a closed -manifold; the example in [4] is obtained by composing the time map, large enough, of a very specific non-transitive Anosov flow by a Dehn twist along a transverse torus. Our result shows that the same construction holds starting with any non-transitive Anosov flow on an oriented 3-manifold. Moreover, for a given transverse torus, our result explains which type of Dehn twists lead to partially hyperbolic diffeomorphisms.
