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.
