Discrete Measures and the Extended Riemann Hypothesis

In this work we show that the Riemann hypothesis for the Dedekind zeta--function $ζ_{\mathrm{K}}(s)$ of an algebraic number field $\mathrm{K}$ is equivalent to a problem of the rate of convergence of certain discrete measures defined arithmetically on the multiplicative group of positive real numbers to the measure $ζ_{\mathrm{K}}(2)^{-1}κq dq $, where $κ$ denotes the residue of $ζ_{\mathrm{K}}(s)$ at $s=1$ and $dq$ the Lebesgue measure.

Harmonic Analysis on the Adèle Ring of $\Q$

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