Abstract
Relying on the Luttinger-Ward theorem we derive a thermodynamically se lf-consistent and scale-independent approximation of the thermodynamic potential for the scalar phi(4)-theory in the tadpole approximation. With certain approximations the presented approach can be extended to quantum chromodynamics (QCD) and it gives support to parametrize the r esults of QCD lattice calculations by suitably modified ideal-gas expr essions.
