On the occasion of CRM’s 50th anniversary in 2018, the Laboratoire de Combinatoire et d’Informatique Mathématique (LaCIM) organizes a month of scientific activities to discuss the state-of-the-art and manifold interconnections between the lively topics that have long been at the core of research at LaCIM: algebraic combinatorics, combinatorial representation theory, Coxeter groups theory, combinatorics of words, discrete geometry, enumerative combinatorics, mathematical computer science and their applications. The scientific activities will be articulated around the confirmed participations of two renowned researchers-in-residence: Mireille Bousquet-Mélou, Directrice de Recherche and Silver Medal of CNRS, and of Ezra Miller, Professor at Duke University; together with a week-long international conference to be held from the 24th to the 28th of September 2018.
