摘要
考虑一类有序分数阶q-差分方程解的存在性和唯一性.先利用q-指数给出该方程解的表达式,再分别利用Banach压缩映像原理、Krasnoselskii不动点定理、Leray-Schauder选择定理证明该方程解的存在性和唯一性.
We studied the existence and uniqueness of solutions for a class of the sequential fractional q-differences equation. Firstly, a representation for the solution to this equation was given via q-exponential. Then the existence and uniqueness of solutions were proven by means of Banach fixed point theorem, Krasnoselskii fixed point theorem and Leray-Schauder alternative theorem.
