Combinatorics Working Seminar

Summer Semester 2017

This is the weekly combinatorics working seminar organized by PhD students and postdocs in the combinatorics group at the University of Vienna. We promote a friendly atmosphere where students and members of the group have the opportunity to present their recent developments and/or interests in an informal setting. For this reason the talks are mainly addressed to students but senior academics are also welcome to attend.

Students and postdocs from other groups are very welcome to join! if you are interested in being added to the mailing list or in presenting a talk please contact Cesar Ceballos (
