$L$ -approximation of $B$ -splines by trigonometric polynomials

A. G. Babenko, Yu. V. Kryakin

This note is a continuation of our papers [1,2], devoted to $L$ -approximation of characteristic function of $(- h, h)$ by trigonometric polynomials. In the paper [1] the sharp value…

Functions measuring smoothness and the constants in Jackson--Stechkin theorem

A. G. Babenko, Yu. V. Kryakin

This paper is devoted to the equivalence of two type direct theorems in Approximation Theory: a) for smooth functions (Favard's estimates). b) for arbitrary continuous function (Ja…
