Three Talks in Combinatorics

a recurring event at Universitat de Barcelona

Every once in a while we gather three researchers and let them give about 30-minute-talks in combinatorics.
The event takes place at Edifici històric of Universitat de Barcelona. The room differs from time to time.
To see the abstracts hover over the titles.
