Foundation of the Nonlocal Model of Quantized Fields
The fundamental problems of quantum field theory (QFT) are a unified description of particle physics phenomena and a strict mathematical formulation of the basic principles of the theory. One of the directions in which these problems are investigated, is called the axiomatic approach in QFT. Bogolubov, Medvedev and Polivanov’s (BMP) formulation, for example, is based on the variational derivative method of the S-matrix and on the causality condition. Another field approach is connected with names of Garding, Wightman, Haag, Lehmann, Symanzik and Zimmermann, etc. The mathematical fundamentals of QFT were given in a series of monographs [see, for example, Bogolubov et al. (1958), Streater and Wightman (1964), Jost (1965), and Bogolubov et al. (1975)].
