摘要
考虑非线性时滞差分方程xn+1- xn+ pnf( xn- l1,xn- l2 ,… ,xn- lm) =0 ,n =0 ,1 ,2 ,… .获得了方程所有解振动的充分条件 ,推广并改进了现有文献中的结果 .
Consider the nonlinear delay difference equation of the form x\-\{n+1\}-x\-n+p\-nf(x\-\{n-l\-1\},x\-\{n-l\-2\},\:,x\-\{n-l\-m\})=0,\ n=0,1,2,\:. This paper obtain sufficient conditions for the oscillation of all solutions of this equation. Which extend and improve some well-known results in the literature.
