We showed, that optimal orthonormal systems on unit circle for construction of the best linear methods of approximations are the systems of Takenaka-Malmquista. The best linear method of approximations of bounded harmonic functions on the compact subsets of unit disk are determined.. Product Description popup.authors popup.nrat_date 2020-04-02 Close
