GoTh Workshop: Groups of Thompson and their relatives

18-22.9.2023, Otto-von-Guericke-Universität Magdeburg
Around six decades ago, Richard Thompson introduced a triad of groups of homeomorphisms F, T and V, which were later popularized due to their remarkable combinatorial, algebraic, analytic, and cohomological properties. This workshop is part of a sporadic conference series revolving around Thompson's original groups, their generalizations, and related variants. Many experts in the area will gather to discuss recent developments.

How to get to Magdeburg:
Magdeburg is well-served by frequent train connections to other larger cities, such as Hannover, Berlin, or Leipzig. Magdeburg is almost equidistant to those three cities, so getting to any of them means that you can easily get to Magdeburg from there.

- Traveling by train to Magdeburg Hbf, which stands for "Magdeburg Hauptbahnhof", i.e., Magdeburg Main Train Station. Most train connections and tickets can be booked directly via Deutsche Bahn or
You can also buy the tickets (also for local trams and buses) via their app or DB machines.
Suggestion: when looking for train connections on the Deutsche Bahn website, always unmark the "Show fastest connections" option (in case you are booking in German, unmark "schnellste Verbindungen anzeigen").

- Traveling by plane: the most convenient airport nearby is Berlin Brandenburg Airport (BER). It has its own train station within the airport. There are plenty of train connections between BER and Magdeburg, the ride usually takes about 2h30min in the standard route. The closest airport to Magdeburg is actually Leipzig/Halle (LEJ), around 1h40min by train. Though it is quite small, operating mostly local flights (and the eventual popular connection Germany - Spain). The closest super hub is Frankfurt Airport (FRA), though it is still a long train ride away from Magdeburg (between 4h20min and 5h). FRA has the advantage of having good services/facilities. You might want to consider Munich Airport (MUC). It is almost as well connected as FRA with a not-much-worse train ride (45min from the airport to the city center, then slightly over 4h from Munich to Magdeburg).

Workshop venue:
The tram stop closest to the Math Department is Universität, and the department is located in buildings 2 and 3 of the campus Universitätsplatz. Here you can find a map, along with various nearby restaurants.
All talks will take place in room G03-106 (in Building 03 on the main campus).

Online participation:
All talks will be streamed online and anyone interested can join; no registration is necessary. The ID of the Zoom room is 613 2292 0012, and the password is the blank in the following sentence: "This is a workshop about ________ groups." (8 letters, first letter a capital T, all other letters lower case, rhymes with "Johnson").
