The basic Feynman integral is calculated, needed in the description of the complicated anisotropic and constrained systems. A new approach is proposed for studying all possible phases in mixed ferro-antiferromagnetic compounds of the RADP type, the pase diagram "concentration-temperature" is constructed. The structural characteristics of the Ising magnetics are investigated, a unified method for the study of the universal critical exponent of the correlation function and its critical amplitude is developed. For the spin-1/2 Heisenberg model on a two-layer structure with a hexagonal lattice and a frustrating inter-layer interaction in an external magnetic field, an effective classical lattice gas model is obtained. For the first time, the analytical solutions of the autotypical equations for four-color and multiple-color printing are obtained, and a new technology of color printing ICaS-ColorPrint is created. On the basis of the non-homogeneous mean field approximation and the analysis of zeroes of the partition function in the complex plane, the universal characteristics of the critical behavior of the Ising and Potts models on the scale-free network with an annealed or quenched disorder are found. A unified approach is developed for the investigation of phase transitions in two-dimensional spin models with non-correlated and correlated structure defects. The results of the application of the statistical-physics apparatus to the analysis of the processes of human activity are presented.
