偶数阶中立型差分方程的振动性

Oscillation of Solution for Even Order Neutral Difference Equations

研究了偶数阶非线性中立型差分方程Δm - 1 (anΔ(xn +pnxτn) ) +f(n ,xgn) =0的振动性 .通过对其最终正解作Riccati变换 ,得到相应的Riccati型差分不等式 。

Some Riccati type difference inequalities are established by using Riccati technique for following even order neutral difference equation Δ m-1 (a n Δ( x n+p nx τ n ))+f(n,x g n ) =0, and using these inequalities,some oscillation criteria for above equation are obtained.
