Abstract
Given a regular foliation of a Riemannian manifold, we may ask how complex is the foliation. Among the tools introduced to quantify the complexity of a foliation we have the transverse Laypunov exponents and the geometric entropy. Both tools were shown to be extremely importante to capture dynamical informations of a foliation, although, there is still a huge variety of open questions on this field. The main goal of this project is to make use of recent dynamical tools to better understand the dynamical behavior of a generic foliation. To this end we will study:1. which conditions are sufficient to imply that the transversal Lyapunov splitting is dominated;2. under what conditions the transverse invariant measures are absolutely continuous with respect to the Lebesgue measure on the transversals;3. how can we perturb a foliation with zero geometric entropy to obtain a foliation with positive geometric entropy (if it is possible) and how can we remove zero Lyapunov transverse exponents. We holpe that once developed, the tools cited above comes to be of great importance in the study of the dynamics of a foliation. (AU)
