EXACT RENORMALIZATION GROUP EQUATIONS AND THE FIELD THEORETICAL APPROACH TO CRITICAL PHENOMENA
C. Bagnuls, Claude Bervillier
After a brief presentation of the exact renormalization group equation, we illustrate how the field theoretical (perturbative) approach to critical phenomena takes place in the more general Wilson (nonperturbative) approach. Notions such as the continuum limit and the renormalizability and the pressure of singularities in the perturbative series are discussed.
