摘要
研究了一类具有多个变滞量的变系数的二阶中立型差分方程的解的振动性,得到了该类方程振动及其解的一阶差分振动的充分条件.
The oscillation problem for a class of the second order neutral difference equations with several variable delay arguments and variable coefficients was studied. A sufficient condition was obtained for the oscillation of the equation and the first order difference of the solution.
