Discountingtheexact orderoftransition we may classify a phase transition in any case with regard to the continuity of the entropy.

Λ vary to account for the change in the degrees of freedom over which we take the path integral, so that the partition function is in fact independent of the scale at which we deﬁne our theory, provided this scale is below our initial cut–oﬀ Λ0. The fact that the couplings themselves vary, or ‘run’, as we change the scale is an
