A Class of Nonlinear Integral Equations

Author(s): MARIA DOBRIČšOIU

Abstract: Using the Contraction Principle and the General Data Dependence Theorem, several results of existence and uniqueness and of continuous dependence of data of the solution of a class of integral equations with modified argument from physics, that is a mathematical model reference with to the turbo-reactors working: x(t )= abK(t ,s)·h( s,x(s) ,x(a), x(b)) ds+f(t) ,t[a,b ], where a,b, a<b, K: [a,b] ×[a,b] , h: [a,b]× 3, f: [a,b] and x:[a,b] are given. Also, an example is given.

Antiperiodic Solutions for Shunting Inhibitory Cellular Neural Networks with Nonlinear Behaved Functions and Mixed Delays

Author(s): WENGUI YANG AND QINGBO ZHAO

Abstract: In this paper, a class of shunting inhibitory cellular neural networks (SICNNs) with nonlinear behaved functions and mixed delays are are considered. Sufficient conditions for the existence and globally exponentially stability of the antiperiodic solutions are established, which are new and complement previously known results. An example is employed to illustrate our feasible results.
