"Renormalisation: classical dynamics hiding in quantum field theory"

Lab. Physique Théorique (LPHT), Univ. Paris-Sud XI (Orsay, France)
We shall review how renormalization combines locality, scale analysis
and power counting into a flow for the constants of quantum field theory.
We shall also indicate briefly how to extend renormalization to non-local
quantum field theories such as those considered in the context of quantizing gravity
