Abstract

In this article, we study the \(\ell^p\)-maximal regularity for the fractional difference equation $$ \Delta^{\alpha}u(n)=Tu(n)+f(n), \quad (n\in \mathbb{N}_0). $$ We introduce the notion of \(\alpha\)-resolvent sequence of bounded linear operators defined by the parameters \(T\) and \(\alpha\), which gives an explicit representation of the solution. Using Blunck's operator-valued Fourier multipliers theorems on \(\ell^p(\mathbb{Z}; X)\), we give a characterization of the \(\ell^p\)-maximal regularity for \(1 < p < \infty\) and \(X\) is a UMD space.

2 阶分数差分方程的最大正则性
在本文中,我们研究了分数差分方程 $$ \Delta^{\alpha}u(n)=Tu(n)+f(n), \quad (nin \mathbb{N}_0) 的 \(ell^p\)-maximal regularity。我们引入了有界线性算子的有界(T)和(alpha)残差序列的概念,它给出了解的明确表示。利用布伦克关于\(\ell^p(\mathbb{Z}; X)\)的算子值傅里叶乘数定理,我们给出了对于\(1 < p < \infty\)和\(X\)是UMD空间的\(ell^p\)-最大正则性的描述。更多信息请参见 https://ejde.math.txstate.edu/Volumes/2024/20/abstr.html。
