摘要
用分析的方法研究了一类具有连续变量的高阶非线性时滞差分方程的振动性,得出了该类方程所有有界解振动的几个充分条件,同时得出了该类方程振动的充分条件.
By using the method of analysis,the oscillation for a class of the higher order nonlinear delay difference equations with continuous arguments is studied.Some sufficient conditions are obtained for oscillation of all bound solutions of the equations and oscillation of the equations.
