title: Renormalization group flow equations with full momentum dependence.
abstract: After a short elementary introduction to the exact renormalization group for the effective action, I discuss a particular truncation of the hierarchy of flow equations that allows for the determination of the full momentum of the n-point functions. Applications are then briefly presented, to critical O(N) models, to Bose-Einstein condensation and to finite-temperature field theory.
