摘要
研究了一类有序分数阶q-差分系统解的唯一性和存在性.首先利用q-指数函数给出了该方程解的表达式,然后分别利用Leray-Schauder选择定理、Krasnoselskii不动点定理和Banach压缩映像原理证明了该系统解的存在性和唯一性.
We study the existence and uniqueness of solutions for a class of the sequential fractional q-differences system.Firstly,using q-exponential,a representation for the solution to this equation is given.Then the existence and uniqueness of solutions are proven by using Leray-Schauder alternative theorem,Krasnoselskii fixed point theorem and Banach contraction mapping principle.
