摘要
研究了一类带有非局部分数阶边值条件的分数阶差分方程解的存在性与唯一性.首先给出了这个问题解的表达式,然后分析了格林函数的一些性质,并运用压缩映像原理,Brouwer定理以及Krasnoselskii定理证明了该问题解的存在唯一性.所得结论推广了现有文献中的一些结果,并给出了具体例子用以说明文中的主要结论.
We study the existence and uniqueness of solution for a class of fractional difference equation with nonlocal fractional boundary conditions. Firstly we give a representation for the solution to this problem. Then, we analysis some properties of the Green's function and prove the existence and uniqueness of solution by using the contraction mapping theorem, the Brouwer theorem, and the Krasnosel'skii theorem. The results extend and improve the results given in literatures. An example is given to illustrate our main results.
