The purpose of the Japan Europe Number Theory Exchange Seminar is to give an opportunity for researchers in Japan and Europe to present their research projects by giving short talks (30 mins). The target audience are researchers in number theory.

このセミナーが、打ち解けた雰囲気の中海外の研究者の前で短めの英語講演ができる気軽な機会を、日本国内の学生や若手研究者のみなさまに提供できれば幸いです!

If you would like to give a talk, please

Participants do not need to register. The Zoom Meeting ID can be found below.

The next meeting will be on October 26th 2021, 17:00 (JST: Tokyo), 10:00 (CET: Berlin, Paris, Madrid,...)
