Abstract: This paper is dedicated to the study of the problem of asymptotic stability for general non-autonomous dynamical systems (both with continuous and discrete time). We study the relation between different types of attractions and asymptotic stability in the framework of general non-autonomous dynamical systems. Specially we investigate the case of almost periodic systems, i.e., when the base (driving system) is almost periodic. We apply the obtained results we apply to different classes of non-autonomous evolution equations: Ordinary Differential Equations, Functional Differential Equations (both with finite retard and neutral type) and Semi-Linear Parabolic Equations.

Keywords and phrases: global attractor, non-autonomous dynamical system, asymptotic stability, almost periodic motions, semi-linear parabolic equation.
