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
