Basic scientific achievements

The main scientific direction is devoted to the study of the embedding theorem to functional spaces. In other words, new Morrey spaces with new parameters are introduced. To study the differential and differential-difference properties of functions from these spaces, both integrable and interpolated theorems are proved using the integral representation. It is also proved that the generalized mixed derivative of the functions from these spaces belong to the Hölder class. It should be noted that in the parametric case, representations of smoothness index is higher than in the case of the classical representation are proved. The obtained theoretical results are effectively applied to the problems of existence, uniqueness, and solvability of solutions of the corresponding partial differential equations. In other words, the high degree of the smoothness index of the considered generalized solutions of equations approximates it even closer to the case of the classical solution.
