Exponential dichotomy of linear systems with almost periodic matrices
R. K. Romanovskii, L. V. Bel'gart Omsk State Technical University
Abstract:
Using the Lyapunov direct method, we establish a condition of exponential dichotomy for the class of dynamical systems under weaker assumptions as compared to the case of an arbitrary continuous matrix on the derivative of the Lyapunov function along the trajectories. By way of application, we obtain a sufficient condition for the dichotomy of a second order almost periodic vector equation in terms of coefficients.
Keywords:
dichotomy, Lyapunov function, hull of an almost periodic matrix.
