This article mainly studies the rate of convergence in the central limit theo-rem for deterministic dynamical systems.We prove the central limit theorem for vn=??J=0n-1v°Tj whereis a H(?)lder continuous observable with a mean of 0 andis a nonuniformly expanding map.After that,we also obtain the convergence rate of vn in the Kolmogorov distance.In addition to nonuniformly expanding systems,our results are also applicable to nonuniformly hyperbolic systems. |
