On the Dissemination of Results on the Optimal Recovery of Information about the State of the System from Incomplete and Inaccurate Data in the Kiprianov Spaces
Abstract
The results related to the restoration of functions in weight spaces from incomplete spectral data are presented. In this regard, the problem of reconstructing the singular elliptic Laplace - Bessel operator and its degrees of the function from the Fourier - Bessel transformation, given only on some convex set in the dual image space, is considered. The results of the paper are transferring of parts of the results for functions from Sobolev spaces and for the Laplace operator that were previously obtained by G.G. Magaril-Ilyaev, K.Yu. Osipenko and E.O. Sivkova to the case of a singular differential B-elliptic Laplace - Bessel operator (I.A. Kipriyanov's term). The problem of optimal reconstruction of the solution of the Cauchy problem for the singular heat equation with the Bessel operator is also considered. Explicit expressions for the optimal recovery method and its errors are given.
