Harmonic Analysis of some arithmetical functions

Number Theory 2020-09-30 v1 Complex Variables

Abstract

We study three functions which are power series in the variable zz, Dirichlet series in the variable ss and with coefficients given by arithmetical functions. A strong point is to relate these functions to some Hilbert spaces. Three main ingredients are used: an estimate of Davenport on sums of M\"obius functions, a result of Lucht on convolutions of arithmetical Dirichlet series and the introduction of an operation \otimes on power series, naturally associated with the mentioned Hilbert spaces.
