Intercity number theory seminar |
The intercity number theory seminar is organized by the Leiden number theory group. It meets every second Friday at one of the participating universities (Leiden, Groningen, Utrecht and Nijmegen).
The seminar is one of the activities of Stieltjes number theory.
Announcements of talks in the intercity seminar are distributed via the Algebra and Geometry mailing list of the Wiskundig Genootschap.
