It allowed to solve some important extremal problems. In particular, assymptotical formulas are got for the upper bounds of deviations of certain linear operators on the classes of functions, defined on the real axis. Order equalities of the best n-term approximations of some classes of functions of several variables are found.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
