The main goal of this trimester is to give to researchers in combinatorics the opportunity to meet and work together. More precisely, we aim at gathering people from the three following wide themes:

These three fields share some common features either via the objects they study or the techniques they involve and some collaborations already exist. But we feel that the three communities will benefit from more exchanges and hope that the trimester will reinforce the already existing links and foster new deep interactions.

The trimester includes: and will host many scientists for long and short visits.
