We are concerned here with the existence of monotonic and uniformly asymptot-ically stable solution of an initial-value problem of non-autonomous delay differential equations of arbitrary (fractional) orders.

We study a semilinear non-autonomous ordinary differential equation (ODE) of order n. Explicit conditions for the existence of n linearly independent and positive solutions on the positive half-line are obtained. Also we establish lower solution estimates.

In this note we apply Avery-Peterson multiple fixed point theorem to investigate the existence of multiple positive periodic solutions to the following nonlinear non-autonomous functional differential system with feedback control

In this work, we consider an impulsive non-autonomous semilinear equation with iterated deviating arguments in a Banach space. We establish the existence and uniqueness of a mild solution. Also we present an example that illustrates our main result.

Abstract In this article, we use the Nehari manifold method to study a class of fourth-order even difference systems. First, show that there exist multiple periodic solutions non-autonomous system. Second, obtain sufficient conditions guarantee existence with prescribed minimal periods autonomous Our results generalize in reference.

In this paper, we are concerned with the approximate controllability results for a class of impulsive functional differential control systems involving time dependent operators in Banach spaces. First, show existence mild solution non-autonomous evolution inclusions separable reflexive spaces help family and generalization Leray-Schauder fixed point theorem multi-valued maps. order to establish...

There is some evidence of the unabated proliferation of employee-autonomous, informal in an enterprise sense, collaborative information technologies (CITs) to perform collaborative activities despite huge investments in CIT enterprise systems. This article will introduce the metaphorical construct of “shadow CIT” (similar to “shadow IT” – Raden, 2005; Schaffner, 2007) to describe the strategic ...
