Le 15 janvier 2013 à 10h30 en B107, Nguyên Hoàng Nghĩa nous parlera de : The Tutte polynomial for matroids, a renormalization group-like approach

Résumé : Using a quantum field theory renormalization group-like differential equation, we give a new proof of the recipe theorem for the Tutte polynomial for matroids. The solution of such an equation is in fact given by some appropriate characters of the Hopf algebra of isomorphic classes of matroids, characters which are then related to the Tutte polynomial for matroids.
