一类非线性差分方程的振动性

Oscillatory a Class of Nonlinear Netural Difference Equations

用Riccati变换方法,获得了一类非线性差分方程 △[an△(bn△(xn-pnxn-r))]+qnf(xn-σ)=0 的振动性的一些结果,并对已知结果做了一些有意义的改进.

In this paper, we obtained some results of oscillatory a class of Nonlinear Netural Difference Equations△[an△(bn△(xn -pnxn-r))] + qnf(xn -σ) = 0 by using Riccati changer our results generalize and improve some known results.
