| Abstract: | Combining with biomedical models,the existence of pseudo almost periodic solution is studied for the cellular neural networks with piecewise constant argument by the definition of pseudo almost periodic function,relevant properties and difference equations.By the continuity of the solution,building a different equation,the sufficient conditions of the existence of pseudo almost periodic solution are given basing on pseudo almost periodic sequence solution of a difference equation and other functions of the equation.The cellular neural networks combines the properties of differential equations and difference equations,and it can be applied in mode recognition,signal processing and imagining memory and so on. |
