โœฆ Synopsis

A unitary method is developed for constructing the Fourier transform of the twopoint Green's functions in local and nonlocal theories with unrenormalizable interactions. The spectral representations of these functions are derived. It is shown that the functions considered have a logarithmic branch point with respect to g for g = 0 in the momentum space.

This paper treats some essential results obtained by the authors in quantum field theory with infinite multiplets. The explicit expression of the matrix of finite Lorentz transformation is found. The interaction of infinite multiplets is studied and its specific properties are shown. The quantizatio
