Renormalization has been recently used in many different contexts : quantum field theory in curved spacetimes, interaction of quantum mechanical atoms with quantum boson fields, algebraic combinatorics, Hopf algebra, counting of points in cones, number theory, etc. The purpose of this workshop is to bring together different communities working with renormalization to exchange their techniques and points of view.
