The aim of the work is to obtain new results on the interaction of elementary particles, processes in quark-gluon plasma, the behavior of correlation functions in nonequilibrium processes and thermodynamic characteristics near critical points, a description of the geometry and physics of charged black holes; to study historical material related to the development of research in theoretical physics in Ukraine. Research methods – analytical calculations using modern methods of theoretical physics, numerical solution of equations, search and study of historiographical sources. In (2 + 1)-dimensional quantum electrodynamics, the structure of an exact polarization operator in the presence of a medium is obtained. The hydrodynamics of stationary states of rarefied gas in a strong external field is developed, the Chapman–Enskog method is generalized. The influence of relaxation processes on hydrodynamic ones in electronic semiconductor subsystem is investigated. An improved description of fluctuations on the development of the Landau concept of an effective Hamiltonian is obtained. For the Dicke superradiation process, a system of kinetic equations with binary field correlations is constructed, suitable for numerical maturation. The properties of the configuration space of a spherically symmetric configuration of electromagnetic and gravitational fields in the general theory of relativity are studied. A quantum model of a charged black hole is constructed. The conditions of dominance of the cosmological constant and its influence on the motion of astrophysical objects are clarified.
