摘要：In this talk, we will discuss a shadowing lemma for nonuniformly hyperbolic maps in Hilbert spaces. As applications, we will show positive Lyapunov exponents of a hyperbolic measure can be approximated by positive Lyapunov exponents of hyperbolic periodic measures
and give a upper bound of the metric entropy using the exponential growth rate of those periodic orbits.
