Path Integrals and Gauge Theories,n.. Unfortunately the discussion of path integral quantization is completely ignored in most standard text-books on field theory, or is given inadequately. I would like to describe the basic idea involved, so that one can proceed to the quantization of gauge theories by this method.

Group Theoretical Approach to Conformal Invariant Quantum Field Theory,tum field theory (QFT). As has been explained in some detail in Symanzik’s lectures (1) such a theory, if it exists, has a good chance of being relevant to the description of the real world in certain high energy limits — or possibly at intermediate energies as was suggested by Wilson (2]. The basic

Use of Invariant Transformations in Problems of Superconductivity, is to show how, by using ideas from quantum field theory, it is possible to formulate the theory of superconductivity from a different point of view which offers some advantages over the usual formulation. By applying the “self consistent quantum field theory”. we have been developing for some year

Short Review of Small-Distance-Behaviour Analysis,Schwinger functions (1). These are the restrictions of the analytic Wightman functions to Schwinger points (2): time components of all arguments imaginary, space components real, or, alternatively, the corresponding analytic continuations of vacuum expectation values (VEVs) of time-ordered products

Quantum Gravity as a Gauge Field Theory,cisely how to obtain Feynman rules for a gauge theory; secondly, the dimensional regularization scheme provides a powerful tool for handling divergencies.. Indeed, several authors have already published work using these methods..

Self-Consistent Quantum Field Theory and Symmetry Breaking,h many of our results in this part help our physical and intuitive understanding of subjects and are also useful for practical computations, some of them are derived by means of certain approximations. A rigorous derivation of these results are presented in part II in which use was made of the path-

Relativistic Strings and Supergauges,ronic world [1], and some of their ramifications. The main point is that a field theory, such as a quark field theory with a gluon, even if it could be in principle correct, is hopelessly remote from the properties of hadrons one is interested in. This is so because in the strong interaction perturb
