Renormalizing the renormalization group pathologies
Physics Reports, 2001Abstract We review the status of the “pathologies” of the Renormalization Group (RG) encountered when one tries to define rigorously the RG transformation as a map between Hamiltonians. We explain their origin and clarify their status by relating them to the Griffiths’ singularities appearing in disordered systems; moreover, we suggest that the best ...

The notion of renormalization group is not well defined. It arises in theories in which a prominent role is played by scale invariance or covariance properties, of various quantities, with respect to a noninvertible transformation of coordinates.

Renormalizing the nonrenormalizable
Physical Review Letters, 1985A perturbatively nonrenormalizable variant of the Gross-Neveu model of Euclidean quantum field theory with bare propagator p/${\mathrm{p}}^{2\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\epsilon}}}$ is considered. We outline a rigorous argument proving that by appropriate choice of the bare coupling constant the model may be renormalized ...

Il Nuovo Cimento, 1965
The origin of the renormalization group is re-examined and various applications of the theory are discussed. The attention is focused on the limitations of these methods, and it is found that supplementary conditions are required besides the group equations in order to get unique results. These additional conditions on the solutions form the very basis
