Abstract
In this paper, mean Li-Yorke chaos and mean sensitivity are investigated in non-autonomous discrete systems \((X, f_{1, \infty })\), where \(f_{1, \infty } = \{f_{i}\}_{i \geq 1}\) is a sequence of self-maps on a metric space X. It is shown that mean Li-Yorke chaos is preserved under iteration for a non-autonomous discrete system with certain continuity. Moreover, sensitivity, Banach mean sensitivity and mean sensitivity of non-autonomous linear discrete systems are characterized, respectively. We provide sufficient conditions under which a mean sensitive non-autonomous discrete system is mean Li-Yorke chaotic.
