چکیده

Résumé. Dans ce travail, un codage symbolique des séries génératrices de Dirichlet généralisées est obtenu par les techniques combinatoires des séries formelles en variables non-commutative. Il permet d’expliciter les séries génératrices de Dirichlet généralisées ’périodiques’ – donc notamment les polyzêtas colorés – comme combinaison linéaire de polyzêtas de Hurwitz. De plus, la version non commutative du théorème de convolution nous fournit une représentation intégrale des séries génératrices de Dirichlet généralisées. Celle-ci nous permet de prolonger les polyzêtas de Hurwitz comme des fonctions méromorphes à plusieurs variables.

Quantum groups and zeta-functions

A q-analogue of the Hurwitz zeta-function is introduced through considerations on the spectral zeta-function of quantum group SUq(2), and its analytic aspects are studied via the Euler-MacLaurin summation formula. Asymptotic formulas of some relevant q-functions are discussed.

Inclusion Properties for a Certain Class of Analytic Function Related to Linear Operator

In this paper, we introduce a new class of analytic functions defined by a new convolution operator La (α, β). The new class of analytic functions Σ a,t α,β (ρ; h) in U ∗ = {z : 0 < |z| < 1} is defined by means of a hypergeometric function with an integral operator associated with the Hurwitz-Lerch Zeta function and differential subordination. The authors also introduces and investigates variou...

Moments of Hypergeometric Hurwitz Zeta Functions

This paper investigates a generalization the classical Hurwitz zeta function. It is shown that many of the properties exhibited by this special function extends to class of functions called hypergeometric Hurwitz zeta functions, including their analytic continuation to the complex plane and a pre-functional equation satisfied by them. As an application, a formula for moments of hypergeometric H...
