$q$-Bounded systems: Common approach to Fisher–Micchelli's and Bernstein–Walsh's type problems

M. S. Martirosyan, S. V. Samarchyan


Abstract: We have developed a new common method to investigate geometrically fast approximation problems. Fisher–Micchelli's, Bernstein–Walsh's and Batirov–Varga's well known results are obtained as applications.

Keywords: fast approximation, n-widths, biorthogonal systems.
