摘要
研究了一类常系数非线性时滞差分方程,利用迭代算法和数学归纳法,论证了初值问题的解的存在唯一性及有界性,利用差分方程的比较定理证明了方程的非振动解的存在性。
In this paper, a nonlinear delay difference equation with constant coefficients is considered. Existence and bound behavior of the solution of initial value problem are demonstrated by iterate algorithm and mathematical induction. The existence of nonoscillate solution is discussed by comparison theoremof difference equation.
