Optimal recovery of elements from Hilbert space and their scalar products by Fourier coefficients known with error
UDC 517.5 In a Hilbert space defined as the image of the unit ball under the action of a compact operator, we solve problems of optimal recovery of elements by their first $n$ Fourier coefficients given approximately.  Similar problems are also solved for scalar products of...
