Renormalization of Self-consistent Approximation schemes Finite Temperature II: Applications to the Sunset Diagram
H. van Hees, J. Knoll
The theoretical concepts for the renormalization of self-consistent Dyson resummations, deviced in the first paper of this series, are applied to first example cases for the -…

Renormalization in Self-Consistent Approximations schemes at Finite Temperature I: Theory
H. Hees, J. Knoll
Within finite temperature field theory, we show that truncated non-perturbative self-consistent Dyson resummation schemes can be renormalized with local counter-terms defined at th…

Exact Conservation Laws of the Gradient Expanded Kadanoff-Baym Equations
J. Knoll, Yu. B. Ivanov, D. N. Voskresensky
It is shown that the Kadanoff-Baym equations at consistent first-order gradient approximation reveal exact rather than approximate conservation laws related to global symmetries of…
