Generalized Hermitean ultradistributions

C. Andrade;  L. Loura — 2009

Mathematica Bohemica

In this paper we define, by duality methods, a space of ultradistributions ω ' ( ℝ N ) . This space contains all tempered distributions and is closed under derivatives, complex translations and Fourier transform. Moreover, it contains some multipole series and all entire functions of order less than two. The method used to construct 𝔾 ω ' ( ℝ N ) led us to a detailed study, presented at the beginning of the paper, of the duals of infinite dimensional locally convex spaces that are inductive limits of finite dimensional...

Mean value theorems for L-functions over prime polynomials for the rational function field

Julio C. Andrade;  Jonathan P. Keating — 2013

Acta Arithmetica

The first and second moments are established for the family of quadratic Dirichlet L-functions over the rational function field at the central point s=1/2, where the character χ is defined by the Legendre symbol for polynomials over finite fields and runs over all monic irreducible polynomials P of a given odd degree. Asymptotic formulae are derived for fixed finite fields when the degree of P is large. The first moment obtained here is the function field analogue of a result due to Jutila in the...
