Abstract

Abstract This paper deals with homogeneous and non-homogeneous fractional diffusion difference equations. The fractional operators in space and time are defined in the sense of Grünwald and Letnikov. Applying results on the existence of eigenvalues and corresponding eigenfunctions of the Sturm–Liouville problem, we show that solutions of fractional diffusion difference equations exist and are given by a finite series.

分数斯特姆-利乌维尔差分问题在分数扩散差分方程中的应用
摘要 本文涉及同质和非同质分数扩散差分方程。空间和时间上的分数算子是在格伦瓦尔德和列特尼科夫的意义上定义的。应用 Sturm-Liouville 问题的特征值和相应特征函数的存在性结果,我们证明分数扩散差分方程的解是存在的,并且是由有限级数给出的。
