Dedekind sums involving Jacobi modular forms and special values of Barnes zeta functions

Abdelmejid Bayad, Yilmaz Simsek (2011)

Annales de l’institut Fourier

In this paper we study three new shifted sums of Apostol-Dedekind-Rademacher type. The first sums are written in terms of Jacobi modular forms, and the second sums in terms of cotangent and the third sums are expressed in terms of special values of the Barnes multiple zeta functions. These sums generalize the classical Dedekind-Rademacher sums. The main aim of this paper is to state and prove the Dedekind reciprocity laws satisfied by these new sums. As an application of our Dedekind reciprocity...

Dirichlet series and uniform ergodic theorems for linear operators in Banach spaces

Takeshi Yoshimoto (2000)

Studia Mathematica

We study the convergence properties of Dirichlet series for a bounded linear operator T in a Banach space X. For an increasing sequence μ = μ n of positive numbers and a sequence f = f n of functions analytic in neighborhoods of the spectrum σ(T), the Dirichlet series for f n ( T ) is defined by D[f,μ;z](T) = ∑n=0∞ e-μnz fn(T), z∈ ℂ. Moreover, we introduce a family of summation methods called Dirichlet methods and study the ergodic properties of Dirichlet averages for T in the uniform operator topology.

Familles de fonctions L de formes automorphes et applications

Philippe Michel (2003)

Journal de théorie des nombres de Bordeaux

Une notion importante qui a émergé de la théorie analytique des fonctions L ces dernières années, est celle de famille. Par exemple les familles de fonctions L interviennent naturellement dans le modèle probabiliste des matrices aléatoires de Katz/Sarnak qui vise à prédire la répartition des zéros des fonctions L . L’analyse des fonctions L en famille intervient également dans la résolution (inconditionnelle) de divers problèmes ayant une signification arithmétique profonde, tel que le problème de...
