One extremal problem is solved for a projection system of points of a single circle in cases of pairwise noncontinuous domains and open sets. A construction of prime ends on Riemannian manifolds was constructed, the theorems on a continuous extension on the boundary of Q-mapping and the Orlicz-Sobolev classes in terms of prime ends are proved.We obtain theorems on the local and boundary behavior of the direct and inverse Q-mappings of the Euclidean space. Numerical models for calculation of energy spectra of electrons and phonons in disordered solids have been developed. The rates of charge carrier recombination in nitride compounds have been studied.
