Oscillation of Solution for Even Order Neutral Difference Equations

摘要/Abstract

摘要:

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,并由此得到若干个该方程所有解的振动准则.

Abstract:

Some Riccati type difference inequalities are established by using Riccati technique for following even order neutral difference equation
Δm-1(anΔ(xn+pnxτn))+f(n,xgn)=0
, and using these inequalities,some oscillation criteria for above equation are obtained.
