Combinatorial Coworkspace 2022

— a session in algebraic and geometric combinatorics —

Haus Bergkranz · Kleinwalsertal · Austria · March 19-27

A “coworkspace” is a place where people come together to work together or simply side-by-side. The goal of our “combinatorial coworkspace” is to give a group of motivated young and promising as well as established mathematicians such a place to explore new directions, applications, cooperations, and alliances within combinatorics and beyond. A context is provided by a suitable number of tutorials and lectures and the beautiful location encourages to take mathematical thoughts outdoors.

Participation is by invitation only.
Martina Juhnke-Kubitzke (Osnabrück) · Thomas Kahle (Magdeburg) · Raman Sanyal (Frankfurt) · Christian Stump (Bochum)

The following schedule is not carved in stone — if you would like to contribute in any way, for example by proposing a talk or a topic for one of the special sessions, please contact us by email or on-side in person.
We aim for a cowork space to which all participants are encouraged to actively participate!
