Smoothness of topological equivalence on the half line for nonautonomous systems
(Cambridge University Press, 2020)
We study the differentiability properties of the topological equivalence between a uniformly asymptotically stable linear nonautonomous system and a perturbed system with suitable nonlinearities. For this purpose, we ...
Perturbation of a nonautonomous problem in ℝn
(2013-08-01)
In this paper, we prove a stability result about the asymptotic dynamics of a perturbed nonautonomous evolution equation in ℝn governed by a maximal monotone operator. Copyright © 2013 John Wiley & Sons, Ltd. Copyright © ...

Almost reducibility of linear difference systems from a spectral point of view
(American Institute of Mathematical Sciences, 2017)
We prove that, under some conditions, a linear nonautonomous difference system is Bylovs almost reducible to a diagonal one whose terms are contained in the Sacker and Sell spectrum of the original system.
In the above ...
Smoothness of topological equivalence on the half line for nonautonomous systems.
(Cambridge University Press, 2019)
We study the differentiability properties of the topological equivalence between a uniformly asymptotically stable linear nonautonomous system and a perturbed system with suitable nonlinearities. For this purpose, we ...
Pullback exponential attractors for evolution processes in Banach spaces: properties and applications
(American Institute of Mathematical Sciences - AIMSSpringfield, 2014-05)
This article is a continuation of our previous work [5], where we formulated general existence theorems for pullback exponential attractors for asymptotically compact evolution processes in Banach spaces and discussed its ...
Existence theorems for some abstract nonlinear non-autonomous systems with delays
(Elsevier Science, 2014-09)
For some abstract classes of nonlinear non-autonomous systems with variable and state-dependent delays existence, non-existence and multiplicity of periodic solutions are discussed. To illustrate the efficiency of the ...
Asymptotic properties of solutions to nonautonomous Volterra difference systems with infinite delay
(2001)
We show that under certain conditions there is a one-to-one correspondence between weighted bounded solutions of a linear nonautonomous Volterra difference system with infinite delay and its perturbed system. Under additional ...
