We show that if ametric space has two uniformly equivalent metrics, then fuzzy entropy is a constant up tothese two metrics. We present a method to construct chaotic fuzzy semidynamical systemswith arbitrary large fuzzy entropy. We also prove that fuzzy entropy is a persistent objectunder a fuzzy uniformly topological equivalent relation. CR - [1] D.
