A model of field theory with phi _d_4 interaction in space-time of d=2,3,4 dimensionality is considered in the paper aiming at the phi _d_4 phase structure of field theory with arbitrary connection constants and temperature. As a result the method of the investigation of the strong connection regime and phi _d_4 phase structure of field theory has been suggested. The phase structure of this model with d=2,3,4 has been investigated. The influence of UV-divergences on the phase formation has been investigated systematically. The paper results may find their field of application in the theoretical investigation of non-equivalent representations of quantum-field modelsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of R...
