Abstract
We present a computational study of the invariant sets visualization method based on ergodic partition theory, firstly proposed in [1]. The algorithms for computation of the time averages of many L1-functions are developed and employed producing the approximation of the ergodic partition of the phase space. The method is exposed in the context of discrete-time dynamical systems, by producing a graphical representation of the phase space in terms of the invariant set structure that gives a substantial insight into the global and local properties of the dynamics. We use the Chirikov standard map in order to show the implementation of our method, followed by applications to other higher-dimensional maps. We extend the study in our next paper [2] by studying the visualization of periodic sets using harmonic time averages constructed in [3].
