Mode d'emploi de la th\'eorie constructive des champs bosoniques (A user's guide to bosonic constructive field theory)
Abstract
We develop in this article the principal constructive arguments used in quantum field theory, limiting us to bosonic theories, for which there does not exist any recent general presentation. The article is primarily written for mathematicians or mathematical physicists knowing the basic arguments of quantum field theory, and desiring to discover a general framework in which they can be made rigorous. It also provides a glimpse of a recent series of articles MagUnt1,MagUnt2 whose aim is to give a constructive definition of rough paths and fractionary stochastic calculus.
