Utrecht       6 & 7 March 2023


The purpose of the meeting is to share ideas and connect up combinatorics in the Netherlands, as well as to showcase the depth and breadth of Dutch combinatorial research.

We've planned a handful of invited speakers, a limited number of short contributed talks, a flurry of lightning talks, and opportunities for informal discussion.

The following speakers have accepted the invitation to speak at our event: Anurag Bishnoi, Timothy Budd, Daniel Dadush, and Krystal Guo.

The activities are planned to take place in the historic centre of Utrecht at the Museum Speelklok. This is within walking distance of Utrecht Centraal train station. Due to logistic difficulties, remote participation is not possible.

Registration is free, but required, through the following link: registration form (deadline 27 February). Included are coffee/tea and a closing borrel on the Tuesday.
