Lower bounds for the degree of approximation [PDF]
Transactions of the American Mathematical Society, 1960 is the optimal degree of approximation of 2W. In this paper we shall give simple methods which permit to find the order of magnitude of Dn(W) for several important classes ?1: for some classes of analytic functions (?6); for the unit ball AP+a of the space CP+a of functions with continuous derivatives of order p, which satisfy a Lipschitz condition ...

Approximation properties of modified Stancu beta operators
Journal of Numerical Analysis and Approximation Theory, 2006 In this paper we give approximation theorems for modified Stancu beta operators of differentiable functions. The Stancu beta operators were examined in [8, 1, 2, 5] and other papers.

Approximation of functions and their conjugates in Lp and uniform metric by Euler means
Demonstratio Mathematica, 2018 For 2π-periodic functions from Lp (where 1 < p < ∞) we prove an estimate of approximation by Euler means in Lp metric generalizing a result of L. Rempuska and K. Tomczak. Furthermore, we show that this estimate is sharp in a certain sense.

Journal of Inequalities and Applications, 2022 In this article, we consider a bivariate Chlodowsky type Szász–Durrmeyer operators on weighted spaces. We obtain the rate of approximation in connection with the partial and complete modulus of continuity and also for the elements of the Lipschitz type ...

Approximation of functions in the generalized Zygmund class using Hausdorff means
Journal of Inequalities and Applications, 2017 In this paper we investigate the degree of approximation of a function belonging to the generalized Zygmund class Z p ( ω ) $Z_{p}^{(\omega)}$ ( p ≥ 1 $p \ge1$ ) by Hausdorff means of its Fourier series.

Degree of Approximation and Green Potential
Journal of Mathematical Extension, 2009 We will relate the degree of rational approximation of a meromorphic function f to the minimum value, on the natural boundary of f, of Green potential of the weak∗ limit of the normalized pole-counting ...

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017 We present the second message of the cycle from two articles where the rearrangement of the order of approximation of the matrix method of numerical integration depending on the degree in the Taylor’s polynomial expansion of solutions of boundary value ...
