About CCG

The combinatorics related to Coxeter groups play a crucial role in many areas of algebra such as graph theory, hyperplane arrangement theory, matroid theory, building theory and many more. This conference explores this crossroads, in particular its aim is to highlight the importance of combinatorial methods for approaching Coxeter group related topics, such as in the recent developments concerning Chow polynomials arising from Coxeter groups. The focus of this workshop is to foster new and existing connections between young researchers in algebra and combinatorics by giving them the opportunity to meet, exchange and start new collaborations.

The workshop starts on Wednesday (30.09) at 9:30 a.m. and ends Friday (02.10) in the afternoon.

How to reach the venue

To reach Bielefeld, you can use the following ways:

  • By air: There are several close airports that have a one way connection from the corresponding main station of the cities via Deutsche Bahn (German train system) to Bielefeld Main Station (Bielefeld Hauptbahnhof):
    • Hannover (HAJ)
    • Düsseldorf (DUS)
    • Berlin (BER)
    The international airport in Frankfurt am Main (FRA) is also an option, but then you need to change trains in order to come to Bielefeld via Deutsche Bahn. We recommend in this case to evade passing through Cologne (Köln) Main Station.
  • By train: The nearest train station is that of Bielefeld (Bielefeld Hauptbahnhof). German train is not reliable so please plan with enough time to switch trains or take delays into account.
  • By car: Bielefeld is well-connected to the A2/A33 freeway. The address for the University is Universitätsstraße 25, 33615 Bielefeld. There are several options for free parking at the University.
  • In order to reach the University we recommend using tram line 4 in direction "Lohmannshof" and get off at "Universität". All tram lines in Bielefeld share the same three stops in the city center which are "Hauptbahnhof", "Jahnplatz" and "Rathaus". The tram is not free you need to have a valid ticket in order to use it otherwise you might get fined.

Accommodation

If you receive funding from the workshop, we have reserved accommodation at the Locals Stadthotel Bielefeld.

Address:
Locals Stadthotel Bielefeld
Niederwall 31-35
33602 Bielefeld

How to reach the University:
From the hotel, it is just a short walk (approx. 3–5 minutes) to the central tram stops "Rathaus" or "Jahnplatz". From either stop, take tram line 4 (direction "Lohmannshof") directly to the stop "Universität" (approx. 7–10 minutes).

Food and Drinks on Campus

The canteens and cafeterias on campus are run by the Studierendenwerk Bielefeld. The lecture hall X-E0-002 is located in building X, so the two closest options are only a short walk from the talks.

Payment:

  • Please bring a card: payment at the tills works with girocard/EC card, credit card, Apple Pay or Google Pay. Do not rely on cash.
  • The reduced student price is only granted when paying with a UniCard/HochschulCard. As an external guest you will always be charged the guest price, no matter which means of payment you use.
  • If you would like a chargeable card, the Studierendenwerk issues a ServiceCard at the Servicepoint in building X (deposit of 5 €); it can be topped up there and at the top-up machines in building X.

Locations on Campus Bielefeld:

  • Mensa X (building X, main canteen, directly next to the lecture hall) — Mon–Fri 11.30 a.m. – 2.30 p.m.
  • Cafeteria X (building X, snacks and coffee) — Mon–Fri 7.45 a.m. – 4.00 p.m.
  • sowls (main university building) — Mon–Thu 8.00 a.m. – 8.00 p.m., Fri 8.00 a.m. – 4.30 p.m.
  • Poolbar (main university building) — Mon–Fri 11.00 a.m. – 4.30 p.m.
  • HSBI Cafeteria (foyer of the HSBI, a few minutes on foot) — Mon–Thu 7.30 a.m. – 5.00 p.m., Fri 7.30 a.m. – 4.00 p.m.

The current menus and possible changes to the opening hours can be found at studierendenwerk-bielefeld.de.

Conference Dinner

The conference dinner takes place on Thursday, 1st October, at 7.00 p.m. at the Brauhaus Joh. Albrecht, a brewpub in the old town of Bielefeld.

Address:
Brauhaus Joh. Albrecht
Hagenbruchstraße 8
33602 Bielefeld

How to get there:
From the University: take tram line 4 (direction "Stieghorst") from the stop "Universität" to "Rathaus" (approx. 10 minutes), from there it is a walk of about 5 minutes into the old town.
From the Locals Stadthotel: the restaurant is within walking distance, approx. 5–10 minutes on foot.
From the Main Station: tram line 4 (direction "Stieghorst") to "Rathaus", or a walk of about 15 minutes.
