Abstract
In this text we prove that in generalized shift dynamical system for finite discrete with at least two elements, infinite countable set and arbitrary map , the following statements are equivalent: - the dynamical system is Li-Yorke chaotic; - the dynamical system has an scrambled pair; - the map has at least one non-quasi-periodic point.
