International Seminar

About D · M · Y

The Dawn · Midi · Yofuke International Seminar presents a mix of colloquium and research talks on focused themes in arithmetic geometry. The intention is to both introduce classical topics to a wider audience, as well as report on recent progress.

Talks will be held over Zoom at 08:00 EDT on each date. If you are interested in attending, please contact one of the organizers.
