                                    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.
