Renormalization of Φ-derivable approximations in scalar field theories
Jean-Paul Blaizot, Edmond Iancu, Urko Reinosa
We discuss the renormalization of Φ-derivable approximations for scalar field theories. In such approximations, the self-energy is obtained as the solution of a self-consistent equ…

Resummation in hot field theories
Urko Reinosa
We consider a scalar theory at finite temperature in the 2PI resummation scheme, including phi^3 and phi^4 interactions. Already at the one loop level in this scheme, we have to de…

Renormalizability of Phi-derivable approximations in scalar phi^4 theory
Jean-Paul Blaizot, Edmond Iancu, Urko Reinosa
We discuss the renormalizability of Phi-derivable approximations in scalar phi^4 theory in four dimensions. The formalism leads to self-consistent equations for the 2-point and the…
