Renormalization of certain integrals defining triple product L-functions

Renormalization of Certain Integrals Defining Triple Product L-functions

We obtain special values results for the triple product Lfunction attached to a Hilbert modular cuspidal eigenform over a totally real quadratic number field and an elliptic modular cuspidal eigenform, both of level one and even weight. Replacing the elliptic modular cusp form by a specified Eisenstein series, we renormalize the integral defining the triple product L-function in order to obtain...

Hadamard Product of Certain Classes of Functions

In this paper we consider the Hadamard product ? of regular functions using the concept of subordination. Let P (A,B) denote the class of regular functions subordinated to the linear fractional transformation (1 +Az)/(1−Bz), where A+B 6= 0 and |B| ≤ 1. By P (A,B) ? P (C,D) we denote the set {f ? g : f ∈ P (A,B), g ∈ P (C,D)} . It is known ([3], [7]), that for some complex numbers A,B,C,D there ...

Nonvanishing of certain Rankin-Selberg L-functions

In this article we prove that given a holomorphic cusp form f and any point s0 in the complex plane, there is a holomorphic cusp form g such that the Rankin-Selberg L-function L(s, f × g) is non-zero at s0. Résumé: Dans cet article, on prouve le résultat suivant. Etat donné une forme holomorphe cuspidale f et un point quelquonque du plan complexe, il existe une forme holomorphe cuspidale g tell...

p-adic measures and square roots of special values of triple product L-functions

Introduction Let p be a prime number. In this note, we combine the methods of Hida with the results of [HK1] to define a p-adic analytic function, the squares of whose special values are related to the values of triple product L-functions at their centers of symmetry. More precisely, let f , g, and h be classical normalized cuspidal Hecke eigenforms of level 1 and (even) weights k, l, and m, re...
