Abstract
The temperature renormalization group equation (TRGE) is compared with a diagrammatic expansion for the (ϕ4)4-theory. It is found that the one-loop TRGE resums the leading powers of temperature for the effective mass. A two-loop contribution to TRGE is required to do the leading resummation for the coupling constant. It is also shown that the higher order TRGE resums subleading powers of temperature.
