The procedure is based on an exact evolution equation for the effective action, and recovers usual renormalization results.Based on a talk given in the "Workshop on Recent Advances in Particle Physics and Cosmology", Thessaloniki 2005High Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
