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.


If you would like to give a talk, please
register here.

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

This seminar is finished for this semester. We might continue it in the future.


All meetings are taking place online via Zoom.
