非线性四阶差分方程的振动性

Oscillation of Nonlinear Forth Order Difference Equations

利用一些差分方程振动性的已有结论,建立了一类非线性四阶差分方程解的振动性的一些充分条件。文中定理对已有结果进行了改进。

In this paper,we use the existing conclusions about oscillation of difference equations,and obtain some new sufficient conditions for the oscillation of all solutions of the nonlinear fourth order differerence equations.Our results generalize and improve some known results of the nonlinear difference equations.
