On Leray’s FormulaWe transform Leray’s formula on the Fourier transform of a radial function in such a way that it preserves the form of a one-dimensional Fourier transform and the transformed function is close to the initial function as much as possible.

Reconstruction Operator of Functions from the Sobolev SpaceFor function classes with dominant mixed derivative we study the reconstruction operator of functions by their values at a given number of nodes. We prove that the error by the order coincides with the corresponding orthogonal width.

Laplace–Borel Transformation of Functions Holomorphic in the Torus and Equivalent to Entire Function to constructing some growth theory of this class with the use of the growth theory of entire functions of several variables. This approach is illustrated by investigations of Laplace–Borel transformation of functions of ..
