Equality of Kolmogorov-Sinai and permutation entropy for one-dimensional maps consisting of countably many monotone parts
Tim Gutjahr, Karsten Keller
In this paper, we show that, under some technical assumptions, the Kolmogorov-Sinai entropy and the permutation entropy are equal for one-dimensional maps if there exists a countab…
