In this paper we investigate the existence of the periodic solutions of a quasilinear differential equation with piecewise constant argument of generalized type. By using some fixed point theorems and some new analysis technique, sufficient conditions are obtained for the existence and uniqueness of periodic solutions of these systems. A new Gronwa...

This paper is concerned with existence, uniqueness and global exponential stability of a periodic solution for recurrent neural network described by a system of differential equations with piecewise constant argument of generalized type (in short DEPCAG). The model involves both advanced and delayed arguments. Employing Banach fixed point theorem c...

We study scalar advanced and delayed differential equations with piecewise constant generalized arguments, in short DEPCAG of mixed type, that is, the arguments are general step functions. It is shown that the argument deviation generates, under certain conditions, oscillations of the solutions, which is an impossible phenomenon for the correspondi...

Bidirectional associative memories (BAMs) have been extensively applied in autoassociative and heteroassociative learning. However, the research on the implementation of BAM neural networks model with the effects of the constant delay is relatively few. The present work accumulates the global exponential stability criteria for the BAM neural networ...

In this paper, we are concerned with the oscillation of solutions to a class of third-order nonlinear neutral dynamic equations on time scales. New oscillation criteria are presented by employing the Riccati transformation and integral averaging technique. Two examples are shown to illustrate the conclusions.

In this paper, we investigate the models of the impulsive cellular neural network with piecewise alternately advanced and retarded argument of generalized argument (in short IDEPCAG). To ensure the existence, uniqueness and global ex- ponential stability of the equilibrium state, several new sufficient conditions are obtained. The method is based o...

This work presents a mathematical model that assumes the existence of an animal population that, from an epidemiological point of view, is being affected by an infectious disease of the SIR type and, from an ecological perspective, its habitat is in a gradual process of fragmentation. We make a first approximation to its dynamic behavior through gr...

The main goal of our paper is to obtain sufficient conditions for the asymptotic equivalence of a linear differential system and a quasilinear system of impulsive differential equations with piecewise constant argument of generalized type, in short IDEPCAG. A deviating argument is of the advanced and delayed type. As an auxiliary result, the struct...
