The project CARMA of the French National Research Agency is devoted to Algebraic Combinatorics, Resurgence, Moulds and Applications; it was started in 2012.

The conference CARMA2017 ( is aimed as being an important event among the ones organized within this project, to take stock of the numerous recent achievements and publications on these topics, from people both outside and inside of this research group. The conference will notably emphasize the role of Hopf algebraic techniques and related objets (e.g. Rota–Baxter algebras, operads, Ecalle’s mould calculus), which have lately proved pervasive in combinatorics, but also in many other fields, from multiple zeta values to the algebraic study of control systems and the theory of rough paths. Beside that, the last 4 years have seen a burst of articles in various parts of theoretical Physics that enhance the role of resurgent functions, beyond their original applications in dynamical systems and these will also be among the topics of the conference. It is a good moment for an extended diffusion of the combinatorial constructions developped within the CARMA project in connection with Ecalle’s powerful theories, and also to pave the way for a better under standing of some crucial questions being currently studied in many domains of Mathematics or Physics which involve the very same type of objects, and where the activity is intense.

The workshop will thus be a timely opportunity for scientists belonging to distinct communities, though sharing similar techniques, to report on their latest results and exchange ideas.

The selection of talks puts the accent on algebraic combinatorics and moulds, with a component on alien differential calculus and resurgence in Physics.

A volume of Proceedings will be published.
