| Abstract: | A general analysis of finite temperature renormalization group equations for massless theories is presented. It is found that in a direction where momenta and temperature are scaled up with their ratio fixed the coupling constant behaves in the same manner as in zero temperature and that the asymptotic freedom at short distances is also maintained at finite temperature. |
