Düsseldorf-Münster Model Theory Seminar,
some Fridays, varying time and place

   Düsseldorf Doctoral Research Seminar in Pure Mathematics



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 is 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:

                   Peter Arndt
                   David Bradley-Williams
                   Kevin Langlois


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

Abstracts:



  • Monday, 17. 12. 2018:     Aleksandra Kwiatkowska (Münster), Kechris-Pestov-Todorcevic correspondence and its application to homeomorphism groups of dense trees

    I will discuss the Kechris-Pestov-Todorcevic correspondence relating the Ramsey property for a family of finite structures and dynamical properties, like the extreme amenability, of the automorphism group of the corresponding countable limit structure. I will then apply this correspondence to compute universal minimal flows of homeomorphism groups of dense trees called Ważewski dendrites.
