摘要
考虑如下中立型差分方程其中Pn≥1,m,l为非负整数且m>l,我们获得了差分方程(*)所有解振动及存在正解的充分条件。
Consider the neutal difference equationWhere Pn≥1, m. l are nonnegative integers and m > l We establish sufficient Conditions for theoscillation of eq(*). We also obtain a sufficient Condition for the existence of a positive solutionof eq(*)
