摘要
考虑中立型时滞差分方程:Δxn-pnxn-k+qnxn-l=0;n=0,1,2,….其中,pn,qn(n=0,1,2,…)是实数,且pn≥0,qn≥0,k和l是非负整数,得到了临界状态下上述方程所有解振动的一个充分条件.
The authors studied the neutral delay difference equation △（xn-pn^xn-k）＋qn^xn-l=0;n=0,1,2,….where,（n=0,1,2,…） are real number with pn≥0,qn≥0,k and 1 are nonnegative integers.A sufficient condition for the oscillation of all solutions in critical state is obtained.
