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 p

โฆ Synopsis
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 quantization of fields with infinite multiplets is considered and the existence of big free local fields with normal connection between spin and statistics is shown. The generalized Feynman rules are formulated.

Dispersion relations and sum rules are derived for the complex rotatory power of an arbitrary linear (nonmagnetic) isotropic medium showing natural optical activity. Both previously known dispersion relations and sum rules as well as new ones are obtained. It is shown that the Rosenfeld-Condon dispe
