Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 23 novembre 2010 à 14h00 en B311, Adrian Tanasa nous parlera de : Renormalizability in (non)commutative quantum field theory

Résumé : I will introduce in this talk the main ingredients required to obtain a renormalizable model in quantum field theory.
After presenting the main ideas for commutative models, I will generalize this for noncommutative quantum field theory, where usual graphs are replaced by topologically richer ribbon graphs.
