Announcement

The workshop continues the tradition of Prague Combinatorial Workshops held since 1993. Oriented on problems of all fields of graph theory, combinatorics and discrete geometry, it will continue in the spirit and informal working atmosphere of the previous meetings.

The workshop takes place at DIMATIA and the Department of Applied Mathematics of Charles University, Malostranske namesti 25, Prague 1, which is located in a historic building in the center of Old Prague. The workshop is also supported by Computer Science Institute of Charles University.

The workshop participation is by invitation only. Regardless, if you wish to participate, please email the organizers and we will respond to you shortly. In case you need an invitation letter (for example for your visa), please let us know and we will be happy to write one for you.

Coffee breaks and part of the meals are provided by the organizers. However, we will collect a modest fee of EUR 90 towards a fraction of the expenses.

As is the tradition, the program of the workshop is determined from day to day. The afternoons are reserved for discussions and other activities. If you intend to give a talk during the MCW, please let us know a few days in advance.

If you arrive later during the workshop, please register with the secretaries in the room 222 (at the 2nd floor).

On Wednesday afternoon, there will be an awesome social event.

This workshop is part of a project that has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement No 810115)

Facilities

Besides the workshop itself, you are free to use the following facilities of our departments:

  • Two open lounges with tables, chairs and a whiteboard opposite the Lecture Room S5. You can take the lounges on a first come, first serve basis. Great for working on open problems in the afternoon!
  • Two open lounges with tables, chairs and a whiteboard on the third floor, directly above the lounges on the second floor. Same rules apply.
  • Water coolers in the hall with the open lounges -- both on second and third floor.

If you need anything else, contact the organizers.

Travel info (public transport)

For the public transportation you can buy a 90-minute ticket for 40 CZK or 30-minute for 30 CZK in a newsstand or in a vending machine. Some vending machines only accept coins (no credit cards, no paper money).

The ticket needs to be validated (in a magic yellow validating machine with a shining arrow). The validating machines are located inside buses and trams. In the Metro subway system, the machine is located at the entryway to the station.

If you need to find a tram connection, you can use the official website. The department building is located near the tram stop "Malostranske namesti". You can see it from the tram stop. It is this building.
