On the mean value of the generalized Dirichlet L -functions

Rong Ma, Yuan Yi, Yulong Zhang (2010)

Czechoslovak Mathematical Journal

Let q 3 be an integer, let χ denote a Dirichlet character modulo q . For any real number a 0 we define the generalized Dirichlet L -functions L ( s , χ , a ) = n = 1 χ ( n ) ( n + a ) s , where s = σ + i t with σ > 1 and t both real. They can be extended to all s by analytic continuation. In this paper we study the mean value properties of the generalized Dirichlet L -functions especially for s = 1 and s = 1 2 + i t , and obtain two sharp asymptotic formulas by using the analytic method and the theory of van der Corput.

On the orthogonal symmetry of L-functions of a family of Hecke Grössencharacters

J. B. Conrey, N. C. Snaith (2013)

Acta Arithmetica

The family of symmetric powers of an L-function associated with an elliptic curve with complex multiplication has received much attention from algebraic, automorphic and p-adic points of view. Here we examine one explicit such family from the perspectives of classical analytic number theory and random matrix theory, especially focusing on evidence for the symmetry type of the family. In particular, we investigate the values at the central point and give evidence that this family can be modeled by...

On the periodicity of trigonometric functions generalized to quotient rings of R[x]

Claude Gauthier (2006)

Open Mathematics

We apply a method of Euler to algebraic extensions of sets of numbers with compound additive inverse which can be seen as quotient rings of R[x]. This allows us to evaluate a generalization of Riemann’s zeta function in terms of the period of a function which generalizes the function sin z. It follows that the functions generalizing the trigonometric functions on these sets of numbers are not periodic.
