TitreCombinatorics of joint moments of marginals of random density matrices 
RésuméIn this presentation I will describe the different combinatorial objects appearing in the description of moments of products of different marginals of random matrices. In the general case these objects can be seen as (unicellular) combinatorial maps carrying some additional structures. The study of their combinatorics allows one to study different regimes for the parameters used to define the different marginals and to give freeness results (in the sense of free probability) for some of these regimes. This is a joint work with Luca Lionni and Ion Nechita.
