摘要
研究了一类具有连续变量的线性和非线性偏差分系统的振动问题。给出了系统存在最终正解、负解的充分必要条件及系统振动的若干充分条件。推广和加强了文献［１］的结果。
The oscillation of some linear and non-linear partial difference equations with continuous variables is analysed in this paper. The necessary and sufficient condition for all solutions of ibis system and some sufficient conditions of the oscillation are developed.
