Descrição: Using the Dyson-Schwinger equation, we re-examinate the behavior at finite temperature of the massless <math>\lambda\varphi^{4}\,\!</math> model in a generic D-dimensional Euclidean space. An analysis of the thermal behavior of the renormalized self-energy is done for all temperatures. It results that the thermal renormalized self-energy is positive and increases monotonically with the temperature.
