STRUCTURE OF DIVERGENCES AND PROPERTIES OF DISTURBANCES THEORY SPECIES IN MODELS OF QUANTUM FIELD THEORY

The aim is to develop the method of renormgroup and to apply it for finding of some asymptotics, to investigate the structure of the divergences in the different quantum-field models, to study the influence of the symmetries exising in the theory on their kind, to develop the new approachs in the disturbance theory for approximated computation of the continual integrals of the quantum field theory with any accuracy. The properties of the renormgroup reconstruction in the disturbance theory species have been investigated, the structure of the separating quantum corrections in some important quantum-field models has been determined, its connection with the simmetries existing in the model has been specified, the approach to the quantum-field theory of disturbances has been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
