It is usually contended that the quantum theory of fields is intrinsically divergent. The present paper attempts to show that this divergence is due to the perturbation theory generally employed and not to the field theory itself. By means of a minor modification in the perturbation calculations, the divergent integrals may be given appropriate finite ...

Quantum field theory (QFT) shares many of its philosophical problems with quantum mechanics. This applies in particular to the quantum measurement process and the connected interpretive problems, to which QFT contributes hardly any new aspects, let alone solutions.

The classical theory of fields was developed in Chapter 6. In particular, the electromagnetic field was considered and it is the quantization of this field that is the subject of the present chapter, although it should be noted that other fields may be quantized.

The results of geometric quantization and representation theory are playing an ever increasing role in quantum theory. We review a few examples of this interrelationship in this chapter. Much of quantum field theory involves what must be best described as purely formal relationships, or at least that is the way that we will treat the formalism. We will

Abstract The statistical models we have analyzed so far are defined on a lattice and they have a microscopic length-scale given by the lattice spacing a. In all these models there is, however, another length-scale provided by the correlation length : this is a function of the coupling constants and can be varied by varying the external ...
