On some Hilbert spaces of entire functions associated with the Fourier transform and Dirichlet and Riemann $$L$$-functions. (Sur certains espaces de Hilbert de fonctions entières, liés à la transformation de Fourier et aux fonctions $$L$$ de Dirichlet et de Riemann.) (French. Abridged English version) Zbl 1057.11039
Summary: We consider a Sonine space of entire functions which is related to the Fourier transform, and which depends on a parameter $$\lambda$$. We construct for $$\lambda >1$$ a subspace which is associated with the zeta function of Riemann and we show that the quotient contains vectors intrinsically linked to the non-trivial zeros and to their possible multiplicities. A similar construction is possible for each Dirichlet $$L$$-function.
