This mini-workshop will reflect the recent developments on the crossroads of aperiodic order and number theory. Topics to be covered include k-free systems (and, more generally, B-free systems) in various number fields, discrete integrable systems, properties of the primes, and asymptotics of generating functions in transcendence theory. These fit into the scope of Project A2 of the collaborative research centre TRR 358.

Programme and Schedule
The meeting will move between various rooms (due to the ongoing semester in Bielefeld) in the main university building.
The preliminary programme can be found here: Schedule
We will update this portion of the website as we approach the dates of the meeting.
Registration is not required, however, the organisers would appreciate if you send an e-mail () in case you intend to participate.
Location, Travel, and Accommodation
Travel information to and from the university may be found here. To go from the station or from the city centre to the University and vice versa, use the underground ("Stadtbahn"). Take underground line no. 4 (direction "Lohmannshof") to the stop "Universität".
Update: the so-called "4-er Ticket" for four rides is now obsolete (since November 2025). One can only buy single tickets (either from ticket machines or via the MoBiel app), which are automatically validated. The standard single journey ticket ("Einzelticket": valid for 90 Mins, transfers allowed) costs 3.60 EUR while a short trip ticket ("Kurzstrecke": 4 stops, no transfer) costs 2.00 EUR.
For those staying for the entire week, one could consider buying a 7-day ticket "7 TageTicket" for 28.80 EUR.
Here is a list of hotels within the city centre and the respective tram stops closest to them.
There might also be apartments available in the student accommodation complex at Morgenbreede, which is in a walking distance of the campus. The rooms and other details can be seen here.
For those considering booking their accommodation through AirBnB, apart from those at the city centre, there might be additional options close to the tram stops along line 4 (e.g., close to Rudolf-Oetker Halle or Siegfriedplatz).
