Mean Equicontinuity and Mean Sensitivity for Non-Autonomous Dynamical Systems
摘要
We establish the classical Auslander–Yorke dichotomy and its variants for non-autonomous discrete dynamical systems generated by uniformly convergent sequences of continuous maps. For such systems, sensitivity, equicontinuity, and their variants are shown to be equivalent to the corresponding properties of the associated limit autonomous system. We further obtain a mean version of the Auslander–Yorke dichotomy for uniformly convergent and periodic non-autonomous systems, and show that, in the periodic case, the mean dynamical properties coincide with those of the associated autonomous system.
