Résumé
In this paper we present an alternative proof of the so-named g-lemma of finite-time thermodynamics. It is shown that g-lemma does not impose any restriction on the heat transfer laws or reflect any kind of criterion on whether a heat transfer law proposal could be valid in nature or not, however, the possibilities to work with new heat exchange models can be reached since combinations of heat transfer laws may be treated by using the invariant form of the g function.
