Renormalization of self-consistent -derivable approximations
H. van Hees, J. Knoll
Within finite temperature field theory, we show that truncated non-perturbative self-consistent Dyson resummation schemes can be renormalized with local vacuum counterterms. For th…

Renormalization of self-consistent Schwinger-Dyson equations at finite temperature
H. van Hees, J. Knoll
We show that Dyson resummation schemes based on Baym's -derivable approximations can be renormalized with counter term structures solely defined on the vacuum level. First appli…
