# Timan’s Type Result on Approximation by Algebraic Polynomials

Conference paper

## Abstract

The paper presents two approximation results of the Jackson-Timan type, which were included in my lecture at the All-Union Conference in Approximation Theory (Dniepropetrovsk, June 26–28, 1990).^{y1} The conference was dedicated to the seventieth birthday of Professor Alexander Timan (26.6.1920–13.8.1988). Unfortunately, proceedings of the conference never appeared because of the well-known events in the former Soviet Union, and only the abstracts were published (see [*B*3]). Here we present the approximation method which has been used in the proof of these results. In fact, it can be applied to many other approximation problems of such a kind.
