Abstract

In this paper we develop a Nash-Moser iteration type reducibility approach to prove the (inverse) localization for some dd-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.
