二阶非线性差分方程的振动准则

Oscillations criteria for second order nonlinear difference equations

建立了二阶非线性差分方程 Δ(rnΔxn-1)+PnΔxn-1+qnf(xn)=0的振动准则,所得定理推广和改进了文献中的结果.

Some new oscillation criteria are given for the second order nonlinear difference equationsΔ(r_nΔx_(n-1))+P_nΔx_(n-1)+q_nf(x_n)=-These criteria extend and impove some existing results in the literature.
