摘要
讨论脉冲时滞差分方程xn+ 1- xn +pnxn-l =0 ,n≥ 0 ,n≠ nkxnk+ 1- xnk =bkxnk,k =1,2 ,3…给出了方程所有解振动的充分条件 .
Consider the impulsive delay difference equation x n+1 -x n+p nx n-l =0, n≥0, n≠n k x n k+1 -x n k =b kx n k , k=1,2,3… Sufficient conditions are obtained for the oscillation of all solutions of the equation.
