  • About constants in inequalities of Jackson type for the best approximation of periodic differentiable functions.

    Vestnik St. Petersburg University, p. 33-41

    Let us consider the space of continuous 2pi-periodic functions endowed with the uniform norm.
    The structural properties of the functions are commonly characterized by
    moduli of continuity of various orders. In 1911, D. Jackson established a number of
    fundamental theorems that give estimates for the best approximation by
    the modulus of continuity of the first order for the function and its derivatives.
    These results were later extended to the case when the estimates of the best…

    Let us consider the space of continuous 2pi-periodic functions endowed with the uniform norm.
    The structural properties of the functions are commonly characterized by
    moduli of continuity of various orders. In 1911, D. Jackson established a number of
    fundamental theorems that give estimates for the best approximation by
    the modulus of continuity of the first order for the function and its derivatives.
    These results were later extended to the case when the estimates of the best approximations
    are produced by the moduli of continuity of arbitrary order.
    Inequalities of this type play an important role in the theory of approximation and is
    studied (variously ways) in a large number of works of
    many authors. Similar relations are called direct theorems of approximation theory
    or generalized Jackson inequalities. In this paper for a wide class of spaces
    new estimates were obtained for the constants in the generalized Jackson inequality for
    differentiable functions, in some cases, improving the previously known. The basic apparatus used in the work is approximation methods, which are constructed on the basis of V.A. Steklov functions.
