摘要
通过分析技巧,Riccati变换,研究了一类具变系数的二阶中立型时滞差分方程的振动性,给出了方程振动和解的一阶差分振动的充分条件,并举例说明.
The oscillation of second order neutral delay difference equations with variable coefficients was studied by using averaging technique and Riccati transformation.Some sufficient conditions for oscillation of the equation and the first order difference of the solution were obtained,some examples were used to illustrate the results.
