摘要
研究了二阶非线性时滞差分方程△（an（△（xn＋pnxn-τ））^γ）＋bn（△（xn＋pnxn-τ））^γ＋f（n，xn-σ）=0给出方程振动的充分条件，推广和改进了中立时滞差分方程的许多结果．
This paper mainly studied the oscillation criteria for the second-order nonlinear neutral delay difference equation△（an（△（xn＋pnxn-τ））^γ）＋bn（△（xn＋pnxn-τ））^γ＋f（n,xn-σ）=0meanwhile, we acquired some sufficient conditions for the oscillation of the equation, which has improved and generalized the main results of neutral delay difference equation.
