چکیده

*Correspondence: [email protected] Department of Mathematics, National Taiwan Normal University, 88 Sec. 4, Ting Chou Road, Taipei, 11677, Taiwan Abstract Stability of general equilibrium is usually depicted by a dynamic process of price adjustment which makes the flow of prices eventually come to rest at certain prices, so that the supply and demand of every commodity tend to equal each other. Here we construct a dynamical system of a competitive economy and find that the strict diagonal dominance of the Jacobian matrix of the excess demand function at its equilibrium guarantees the asymptotic stability.

Global Asymptotic Stability of Discrete-Time Recurrent Neural Networks

This paper presents new analytical results on the global asymptotic stability for the equilibrium states of a general class of discrete-time recurrent neural networks (DTRNNs) described by using a set of nonlinear di erence equations. We provide a few suÆcient conditions for the global asymptotic stability of DTRNNs. The resulting criteria include diagonal stability and nondiagonal stability. T...

Innnite Horizon Dynamic Games with Coupled State Constraints

We consider a class of noncooperative open-loop diierential games deened over an innnite time horizon with decoupled controls. These games enjoy the so-called turnpike property under strict diagonal convexity assumptions. We investigate the case where a coupled state constraint is linking all the players in their strategy choices. Taking advantage of the asymptotic stability property of the cla...

Global asymptotic stability for neural network models with distributed delays

In this paper, we obtain the global asymptotic stability of the zero solution of a general n-dimensional delayed differential system, by imposing a condition of dominance of the nondelayed terms which cancels the delayed effect. We consider several delayed differential systems in general settings, which allow us to study, as subclasses, the well known neural network models of Hopfield, CohnGros...

Dynamics of a Delayed Epidemic Model with Beddington-DeAngelis ‎Incidence Rate and a Constant Infectious Period

In this paper, an SIR epidemic model with an infectious period and a non-linear Beddington-DeAngelis type incidence rate function is considered. The dynamics of this model depend on the reproduction number R0. Accurately, if R0 < 1, we show the global asymptotic stability of the disease-free equilibrium by analyzing the corresponding characteristic equation and using compa...
