Combinatorics and interactions

A thematic trimester at the interface between mathematical physics, representation theory and probability

January 9 — March 31, 2017

IHP —Institut Henri Poincaré— Paris

Welcome to the webpage of the thematic trimester combi17 that will be held in January—March 2017 in Institut Henri Poincaré (IHP) in Paris, France. We will keep updating this page until and during the trimester with new information.


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 will include:

And during all the trimester: graduate courses, seminars, see here.

Registration and financial support

Regular registration is now closed. If you are not registered and still want to participate, please contact

We wish to fund the participation of several young mathematicians from scientifically developing countries to the activities of the trimester. Young scientists (master students soon looking for a PhD, PhD students, postdocs) meeting those criteria and interested in the topics of the trimester are much encouraged to apply for a support (including airfare, accommodation, and local expenses) for one to three months to participate in the trimester. Applications, including a CV, a motivation letter and a letter of recommandation, should be sent to by November 1st, 2016.


Full graduate courses will be given by the following lecturers during the trimester. The precise schedule and rhythm are yet to be announced but a tentative schedule and a list of keywords are available on the ''courses'' page.

Mini-courses given by participants may be added to this list at the time of the trimester. A graduate reading seminar will also be organised.

During the school in CIRM, four introductory courses to the themes of the trimester will be given by:
