摘要
研究了一类时滞差分方程的各类性质,指出了该方程振动的充要条件,讨论了方程的周期性并证明了方程的持久性和正解的全局吸引性.
The properties of a class of delay difference equation is discussed.A necessary and sufficient condition for the oscillation of the equation is given,the periodicity of the equation is also discussed and permanence and the global attractivity of the positive solutions of the equation are proved.
