Harmonic Analysis on the Ad\`ele Ring of $\Q$

Classical Analysis and ODEs 2018-03-20 v2

Abstract

The ring of finite ad\`eles \Af\Af of the rational numbers \Q\Q is obtained in this article as a completion of \Q\Q with respect to a certain non--Archimedean metric. This ultrametric allows to represent any finite ad\`ele as a series generalizing mm--adic analysis. The description made provides a new perspective for the adelic Fourier analysis on \Af\Af, which also permits to introduce new oscillatory integrals. By incorporating the infinite prime, the mentioned results are extended to the complete ring of ad\`eles \A\A} of \Q\Q.
