摘要
研究了一类混合二阶q-对称差分方程解的存在性.首先分析了格林函数的性质,然后在Banach代数中利用满足Lipschitz条件的不动点定理,建立了该方程解存在的充分条件,最后通过举例验证了所得结论的合理性.
We study the existence of solutions for a hybrid second-order q-symmetric difference equation.Firstly,some characteristics of the Green function were analyzed,then we obtained sufficient condition for the existence of solutions to this equation using fixed point theorems with Lipschitz condition in Banach algebra.Finally,the main result were verified by an example.
