AI总结:

该研究提出Nash-Moser迭代型可约化方法,证明带幂律长程跳跃的d维离散概周期算子的逆局域化,给出跳跃正则性定量下界,并将已有结果推广至幂律跳跃情形。

摘要:

本文提出一种Nash-Moser迭代型可约化方法,用于证明一类带幂律长程跳跃的d维离散概周期算子的(逆)局域化性质。本文还给出了跳跃正则性的定量下界。作为应用,将文献[Sar82, Pos83, Cra83, BLS83]中的部分结果推广到了幂律跳跃情形。

英文摘要:

In this paper we develop a Nash-Moser iteration type reducibility approach to prove the (inverse) localization for some $d$-dimensional discrete almost-periodic operators with power-law long-range hopping. We also provide a quantitative lower bound on the regularity of the hopping. As an application, some results of \cite{Sar82, Pos83, Cra83, BLS83} are generalized to the power-law hopping case.
