摘要
本文运用母函数等方法得到了一类线性和非线性时滞差分方程的通解 ,从而解决了这类方程的有界保持性问题 .关于 Ladas G提出的差分方程 。
In this paper we obtain a unified solution for a kind of linear and nonlinear delay difference equations from using the spanning function methed.And we provide a partial answer for Ladas G Equation with the necessary condition and sufficient conditions of the boundary and persistence.
