Abstract: From the seventies, people realized that uniform hyperbolicity was less universal property than was initially thought. So the theory was extended in several distinct directions and the theory of non-uniformly hyperbolic systems(Pesin theory) was one of them. Pesin theory and the continuing research give us a rich information about geometric properties of the system. In view of these, we want to study the existence of non-zero Lyapunov exponents of smooth systems and their regularity, especially their continuity. In this talk, we will outline some of our work in this respect.
