| Research Abstract |
An efficient algorithm is given for systematically calculating several statistics such as the invariant measure, the Kolmogorov-Sinai entropy, the autocorrelation function and the power spectrum of chaos in one-dimensional discrete dynamical systems defined by a map. The method is based on the Galerkin approximation to the Frobenius-Perron integral operator. Several numerical examples demonstrate that the proposed method can give approximations with high accuracy to the statistics of various one-dimensional chaos with the absolutely continuous invariant measure under the map.
