Asymptotic formulas for the logarithm of general L-functions at and near s=1
Kohji Matsumoto, Yumiko Umegaki
We consider a general form of L-function L(s) defined by an Euler product and satisfies several analytic assumptions. We show several asymptotic formulas for L(1) and log L(1). In…
A function-field analogue of the Goldbach counting function and the associated Dirichlet series
Shigeki Egami, Kohji Matsumoto
We consider a function-field analogue of Dirichlet series associated with the Goldbach counting function, and prove that it can, or cannot, be continued meromorphically to the whol…
Expressions of content-parametrized Schur multiple zeta-functions via the Giambelli formula
Kohji Matsumoto, Maki Nakasuji
In this article, we consider the expressions for content-parametrized Schur multiple zeta-functions in terms of multiple zeta-functions of Euler-Zagier type and their star-variants…
Double Dirichlet series associated with arithmetic functions II
Kohji Matsumoto, Hirofumi Tsumura
This paper is a continuation of our previous work on double Dirichlet series associated with arithmetic functions such as the von Mangoldt function, the Möbius function, and so on.…
A survey on the theory of universality for zeta and -functions
Kohji Matsumoto
We survey the results and the methods in the theory of universality for various zeta and -functions, obtained in these forty years after the first discovery of the universality…
Numerical computations on the zeros of the Euler double zeta-function I
Kohji Matsumoto, Mayumi Shōji
The distribution of the zeros of the Euler double zeta-function , in the case when , is studied numerically. Some similarity to the distribution of the zeros…
