Infrared behaviour of the pressure in gϕ^3 theory in 6 dimensions

Abstract

In an earlier paper Almeida and Frenkel considered the calculation of the pressure in gϕ^3 theory in 6 dimensions via the Schwinger--Dyson equation. They found, under certain approximations, that a finite result ensues in the infrared limit. We find this conclusion to remain true with certain variations of these approximations, suggesting the finiteness of the result to be fairly robust.
