A unified approach to the asymptotic almost-equivalence of evolution systems without Lipschitz conditions

Abstract

We study the asymptotic behavior of almost-orbits of evolution systems in Banach spaces without any continuity assumptions on either the space or the time dependence. We establish, in a unified framework, standard convergence, ergodic convergence and almostconvergence of almost-orbits for both the weak and the strong topologies on the basis of the analogue behavior of orbits.
