K. Zyczkowski et W. Slomczynski, EXPONENTIAL DECAY OF RELATIVE ENTROPIES TO THE KOLMOGOROV-SINAI ENTROPY FOR THE STANDARD MAP, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 52(6), 1995, pp. 6879-6880
It is shown how to obtain a fast convergence of the relative dynamical
entropies to the limiting Kolmogorov-Sinai entropy for the generating
partition of the standard map.
