چکیده

Let K be an imaginary quadratic field and f an integral ideal. Denote by Cl(f) the ray class group of f. For every non-trivial character χ of Cl(f), we show that L(1, χ)/π is transcendental. If f = f, then complex conjugation acts on the character group of Cl(f). Denoting by Ĉl(f) + the orbits of the group of characters, we show that the values L(1, χ) as χ ranges over elements of Ĉl(f) + are linearly independent over Q. We give applications of this result to the study of transcendental values of Petersson inner products and certain special values of Artin L-series attached to dihedral extensions.

Transcendental values of class group L - functions

Let K be an algebraic number field and f a complex-valued function on the ideal class group of K . Then, f extends in a natural way to the set of all non-zero ideals of the ring of integers of K and we can consider the Dirichlet series L(s, f ) = ∑a f (a)N(a)−s which converges for (s) > 1. After extending this function to (s) = 1, and in the case that f does not contain the trivial character, w...

L - Series and Transcendental Numbers

This paper is a survey of some recent work of mine done jointly with V. Kumar Murty, N. Saradha, S. Gun and P. Rath. In all of these works, the motivating question is the following. Given an automorphic representation π , we consider the L-series L(s, π) attached to π according to the Langlands formalism. We are interested in the possible transcendence of special values L(k, π) when k is a posi...

On the transcendence of certain Petersson inner products

‎We show that for all normalized Hecke eigenforms $f$‎ ‎with weight one and of CM type‎, ‎the number $(f,f)$ where $(cdot‎, ‎cdot )$ denotes‎ ‎the Petersson inner product‎, ‎is a linear form in logarithms and‎ ‎hence transcendental‎.

A problem of Chowla revisited

p ∑ n=1 f (n)= 0 and ∑∞ n=1 f (n)/n = 0? Chowla conjectured that there was no such function. Later that year, Chowla proved a special case of his conjecture and in a subsequent paper, asked if the condition that f (p) = 0 can be dropped. In 1973, Baker, Birch and Wirsing, using the theory of linear forms in logarithms obtained a general theorem, a special case of which implies the conjecture of...

Transcendental values of the digamma function

Let ψ(x) denote the digamma function, that is, the logarithmic derivative of Euler’s -function. Let q be a positive integer greater than 1 and γ denote Euler’s constant. We show that all the numbers ψ(a/q)+ γ, (a, q)= 1, 1 a q, are transcendental. We also prove that at most one of the numbers γ, ψ(a/q), (a, q)= 1, 1 a q, is algebraic. © 2007 Elsevier Inc.
