## Joint value distribution of quadratic L-functions (joint work with Hirofumi Nagoshi)

February 25 at 16:20 - 17:20, 2019

Prof. Hidehiko Mishou (Tokyo Denki University)

In 1975, Voronin established the universality theorem for the Riemann zeta function. Roughly speaking this theorem asserts that any holomorphic function on 1/2<Re(s)<1 can be uniformly approximated b...more

## Symmetric Tornheim double zeta functions

February 25 at 15:00 - 16:00, 2019

Dr. Takashi Nakamura (Tokyo University of Science)

Let $s,t,u \in {\mathbb{C}}$ and $T(s,t,u)$ be the Tornheim double zeta function. We investigate some properties of symmetric Tornheim double zeta functions. As a corollary, we give explicit evaluat...more

## Probability density functions attached to zeta functions

December 6 at 16:00 - 17:00, 2018

Dr. Masahiro Mine (Tokyo Institute of Technology)

The study of the value-distribution of the Riemann zeta function is a classical topic in analytic number theory. In 1930s, Bohr and Jessen proved the existence of a certain limit value regarded as th...more

## On A_2-liftings of sum formulas and Bowman-Bradley type formulas for finite multiple zeta values

November 22 at 11:40 - 12:40, 2018

Dr. Shin-ichiro Seki (Tohoku University)

Both the sum formula and Bowman-Bradley's theorem for multiple zeta values are well known. Recently, Saito and Wakabayashi proved counterparts of these two formulas for A-finite multiple zeta values. ...more

## Generating functions of CM & RM values

November 22 at 10:30 - 11:30, 2018

Dr. Toshiki Matsusaka (Kyushu University)

The special values of the elliptic modular j function j(z) at imaginary quadratic points are known as singular moduli (CM values), and play important roles in algebraic number theory. As a real quadra...more

## Relations between fractal dimensions and arithmetic progressions

October 23 at 11:35 - 12:35, 2018

Mr. Kota Saito (Nagoya University)

In this talk we give estimates for the dimensions of sets in real numbers which uniformly avoid finite arithmetic progressions. More precisely, we say that $F$ uniformly avoids arithmetic progressions...more

## Generalized Erdös and Obláth theorem for polynomial-factorial Diophantine equations

October 23 at 10:30 - 11:30, 2018

Mr. Wataru Takeda (Nagoya University)

Diophantine equations are equations where only integer solutions are accepted. There are many types of Diophantine equations and many results are known. Our Diophantine equation is of the form x^n+y^n...more
