iTHEMS-Kyushu WS - from particles and nuclei to cosmos -

2018-11-27

On Nov.21-22, 2018, iTHEMS-Kyushu WS - from particles and nuclei to cosmos - was held at iTHEMS Kobe office (SUURI-COOL Kobe).
About 20 researchers got together from iTHEMS and Kyushu Univ. to discuss various aspects of quantum many-body theory, quantum field theory and explosive astrophysical phenomena in a very relaxed atmosphere. We will continue to organize such intensive workshop between iTHEMS and Kyushu Univ. in various fields of mathematical sciences in the future.

iTHEMS Public Lectures at RIKEN Kobe Campus Open House

2018-11-27

On Nov. 28, 2018, the annual open campus of RIKEN Kobe was held.
From this year, iTHEMS, which has a Kobe office (SUURI-COOL Kobe), joins this event and organized public lectures "Hot topics in Mathematical Sciences".

This year 's program was
Tetsuo Hatsuda "The world that mathematical sciences open"
Ade Irma Suriajaya "How can something infinite become finite?"
Jeffrey Fawcett "What are genomes? - Toward decoding the language of life - "
Masato Taki and Noriaki Ogawa "Artificial intelligence and its medical application"
Shigenori Otsuka and Shunji Kotsuki "Frontiers in weather forecast research"

The lectures were held in the auditorium at the 8th floor of the Kobe IIB building (iTHEMS office is in the 7th floor). Each speaker gave a 30-40 min. talk followed by lots of interesting questions from the audience. It was amazing to see that iTHEMS researchers are not only extraordinary in their own research but also super science communicators !

Seminar

Number Theory Seminar

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 the probability that values of the Riemann zeta function belong to a given region in the complex plane. After Bohr and Jessen, similar results were proved for many other zeta functions. In this talk, I'll talk about density functions of such probabilities attached to the value-distributions of zeta functions. The density functions, which were named ``M-functions'' by Ihara, are connected with mean values of zeta functions, distributions of zeros of zeta functions, and so on.

Venue: Seminar Room #160, 1F Main Research Building, RIKEN

Theory of Operator Algebras

Theory of Operator Algebras (6th)

December 20 at 15:30 - 17:00, 2018

Dr. Yosuke Kubota (Research Scientist, iTHEMS)

Title: An introduction to operator algebras

Abstract: Operators are linear maps from a (usually an infinite dimensional) linear space (most frequently the Hilbert space) to itself, which is like matrices of infinite degree. Operators form an algebra by obvious addition and multiplication. Operators appear in most of the fields in mathematics, in algebra, in geometry, in analysis, ... Some of the key words at the beginning of these lectures are "spectral theory" "operator algebras" "Tomita-Takesaki theory". These lectures are for non-professional people.
