具连续变量非线性差分方程振动性

Oscillations for Nonlinear Difference Equations with Continuous Arguments

建立了具连续变量非线性差分方程 x(t) -r(t)x(t-τ) + f(t,x(t-σ0 ) ,x(t -σ1) ,… ,x(t -σn) ) =g(t,x(t-δ) )振动性的一些振动准则 ,统一、推广和改进了文献 [1 ～ 6

In this paper,some oscillation criteria for difference equations with continuous arguments have been estabished,which unifies and improves and extend the results of [1～6].
