General Information - Members - Activities - Topology Seminar

This page displays the schedule for the Topology Seminar at the Mathematical Institute.

The seminar takes place on Tuesdays from 5:00 to 6:00 pm, via Zoom. The Meeting-ID is 937 6469 9688. If you want to participate, but are not registered in the Bonn topology mailing list, you can receive the credentials by contacting the organiser.
Tea and cookies will be served at home, if you are lucky, but the Zoom-session should be available at least 30 minutes in advance to chat.
The program of previous semesters is here. If you are interested in giving a talk or want to suggest a speaker, please contact the organiser.
