Theories with Finite Green's Functions

The addition of certain nonrenormalizable terms to the usual action density of a free scalar field leads to nonrenormalizable theories whose exact euclidian and minkowskian Green's functions are less singular than those of the free theory. In some cases, they are finite. One may use lattice met...

Summary:The addition of certain nonrenormalizable terms to the usual action density of a free scalar field leads to nonrenormalizable theories whose exact euclidian and minkowskian Green's functions are less singular than those of the free theory. In some cases, they are finite. One may use lattice methods to extract physical information from these less-singular, nonrenormalizable theories.
