On limit behavior of skew‐product transformation semigroups

This paper introduces both the notions of topological transitivity and topological mixing in the general setting of semigroup actions on topological spaces. A discussion on limit behavior of skew‐product transformation semigroups is presented. The main purpose is to characterize the lifts and the projections of recurrent points, attractors and Morse decompositions for transformation semigroups associated to skew‐product transformation semigroups. The results play a role to the existence of the finest Morse decomposition for control systems and their control flows.
