Abstract
Migdal's recursion relations at low temperature are maximally extended. They are applicable if the order-parameter manifold is an Einstein space, which is precisely the criterion for renormalizability of the corresponding continuum theory. The renormalization-group flow equations are similar to the continuum flow equations as well.
