Resum
Many interesting aspects of the Early Universe involve physics out of
thermal equilibrium, which cannot be studied reliably in the framework of
thermal perturbation theory. After reviewing the shortcomings of the
perturbative approach, we describe the use of the Wilson Renormalization
Group at finite temperature and its application in the cosmological context.
In particular we will discuss thermal masses, damping rates, phase
transitions, and the anomalous baryon number violation above the electroweak
phase transition.
