This seminar has not met since July 2019, and is currently inactive. The present webpage remains as an archive. If you are interested in reviving the seminar, please do! Of course you may contact any of the previous organisers:

                   Peter Arndt (Org.2016-2019)
                   David Bradley-Williams (Org. 2016-2019)
                   Andrea Fanelli (Org. 2016-2018)
                   Alejandra Garrido (Org. 2016-2018)
                   Kevin Langlois (Org. 2018-2019)



This is a seminar with two purposes:

1. We have invited guests giving talks about their research.
2. We give talks among ourselves introducing each other to our own research. These talks should explain basic notions; interruptions, discussion and deviations from the original plan are very welcome.


The standard time and place was Mondays, 16:30-17:30, Room 25.22.03.73. Occasional exceptions from this rule (e.g. when a speaker is not here on Monday) will be marked next to the talk.

If you are interested in speaking or inviting a guest for this seminar, please contact one of the organizers.


This seminar is part of the activities of the Research Training Group GRK 2240: Algebro-geometric Methods in Algebra, Arithmetic and Topology.
