Abstract

We show that a C1C^1-generic non partially hyperbolic symplectic diffeomorphism ff has topological entropy equal to the supremum of the sum of the positive Lyapunov exponents of its hyperbolic periodic points. Moreover, we also prove that ff has topological entropy approximated by the topological entropy of ff restrict to basic hyperbolic sets. In particular, the topological entropy map is lower semicontinuous in a C1C^1-generic set of symplectic diffeomorphisms far from partial hyperbolicity.
