Nonautonomous attractors of skew-product flows with digitized driving systems
Electronic Journal of Differential Equations, 2001 The upper semicontinuity and continuity properties of pullback attractors for nonautonomous differential equations are investigated when the driving system of the generated skew-product flow is digitized.

Abstract and Applied Analysis, 2012 We discuss the existence of subharmonic solutions for nonautonomous second order differential equations with singular nonlinearities. Simple sufficient conditions are provided enable us to obtain infinitely many distinct subharmonic solutions.

Electronic Journal of Differential Equations, 2010 In this paper we use the well-known Schauder fixed point principle to obtain the existence of square-mean almost periodic solutions to some classes of nonautonomous second order stochastic differential equations on a Hilbert space.

A generalisation of Cartwright’s Theorem: nonautonomous differential equations case
Portugaliae Mathematica, 2008 In this article we show that the almost-periodic solutions of a large class of nonautonomous delay differential equations are quasi-periodic. This result is a generalisation of a theorem proved by Cartwright for ordinary differential equations.

Pullback permanence for non-autonomous partial differential equations
Electronic Journal of Differential Equations, 2002 A system of differential equations is permanent if there exists a fixed bounded set of positive states strictly bounded away from zero to which, from a time on, any positive initial data enter and remain.

Periodic solutions of polynomial non-autonomous differential equations
Electronic Journal of Differential Equations, 2005 We present some results on the number of periodic solutions for scalar non-autonomous polynomial equations of degree five. We also consider a class of polynomial equations of any degree. Our results give upper bounds for the number of limit cycles of two-
