Abstract: In the last 30 years, by using foliation theory and group action, Barbot and Fenley developed a powerful tool to qualitatively understand 3-dimensioanl Anosov flows.  In this seminar talk,  we will introduce some basic ideas due to Fenley in this direction.  In particular, we will explain a significant property discovered by Fenley: every free homotopy class of an  R-covered Anosov flow on a hyperbolic 3-manifold contains infinitely many periodic orbits.
