On Non-Renormalizable Interactions, are characterized by having Green functions which are not C∞ in the coupling constant: if this interpretation is correct, the ultraviolet divergences found in the perturbative expansion arise from the non existence of the quantities which are computed in the standard approach (i.e., the coefficient

The Classical Sine Gordon Theory,coming. Thus I was asked to step into his place. I do not know the programme which Fadeev had planned to follow. Since in the seminars by M. Lüscher, A. Luther, and A. Neveu the quantum sine Gordon theory (or, equivalently, the massive Thirring model) will play a central r?le, I finally decided to g

Dynamical Conservation Laws in the Quantized Massive Thirring Model,table lattice quantum field theory. This latter model lives on a one dimensional lattice with spacing a (time remains continuous). Its Hamiltonian is given by . Here, ?., denotes a (one component) fermi operator at site n, G is a renormalized coupling constant, m. is the bare mass, v (G) is a finite

A Tutorial Course in Constructive Field Theory, in dealing with the d = 4 ultraviolet problem. An infinite scaling transformation connects the problem of removing the ultraviolet cutoff with the problem of existence of scaling behavior at the critical point.
