摘要
研究了一类较广泛的二阶中立型非线性时滞差分方程 Δ2 (x(n) +∑li=1ci(n)x(n -mi) ) +∑sj =1 fj(n ,x(n -kj(n) ) ) =0 ,n≥n0的振动性 ,给出了该类方程振动及差分算子振动的判据。
In this paper,the author deals with the oscillation for a class of the second order neutral Nonlinear delay difference equations Δ 2(x(n)+∑li=1c i(n)x(n-m i))+∑sj=1f j(n,x(n-k j(n)))=0,n≥n 0 Oscillation criteria is given out for the equation and the difference operator Δ.
