The main lectures were given by Christos Athanasiadis (Athens) and Kilian Raschel (Tours). Christos Athanasiadis offered us a fascinating tour through various areas where "gamma-non-negativity" occurs, a concept which implies unimodality of coefficients of polynomials. Kilian Raschel, on the other hand, provided us a survey of the exciting new developments in the theory of discrete random walks made possible by the use of analytical and probabilistic tools.
The contributed talks (see the detailed list below) covered various topics, ranging from tableau combinatorics, representation theory, symmetric functions, matroid theory, orbit Dirichlet series, "permutrees", to the asymptotic analysis of lattice paths.
Weather was simply fantastic. Obviously, the lunch breaks were intensively used for swimming in the Wolfgangsee, and for hikes and excursions in the area. The typical "Lotharingien spirit" was (again) very much present during the meeting: intensive exchange of ideas in a family-like atmosphere.
