“…When the constant A is not important, we will also say that Z is coarsely dense in X. It was proved in [1] that in the definition of the coarse entropy of a map, R-separated sets can be replaced with R-dense sets. Namely, instead of the supremum s(f, n, R, δ, x 0 ) of the cardinalities of R-separated sets of δ-pseudoorbits of f of length n starting at x 0 , in formula (1) one can take the minimum r(f, n, R, δ, x 0 ) of the cardinalities of R-dense sets of δ-pseudoorbits of f of length n starting at x 0 .…”
