关于~ $r$阶广义光滑模与代数多项式的最佳逼近的关系

On a connection between a generalised modulus of smoothness of order~$r$ and the best approximation by algebraic polynomials

Mikhail K. Potapov, Faton M. Berisha

摘要:

本文引入了一种广义平移的非对称算子,利用它的平均值定义了广义光滑模,并证明了关于该模的逼近论中的正逆定理。- V dannotrabote vvvoditsya nesimmetricnybrand operator obobbshchennogo sdviga,s ego pomoshchyu opredelyaetsya obbshchennybrand modul' gladkosti i i dlya nego dokazyvaetsya pryamaya i obratnaya teoremy teorii priblizheni.

英文摘要:

In this paper an asymmetrical operator of generalised translation is introduced, the generalised modulus of smoothness is defined by its means and the direct and inverse theorems in approximation theory are proved for that modulus. ----- V dannoǐ rabote vvoditsya nesimmetrichnyǐ operator obobshchennogo sdviga, s ego pomoshchyu opredelyaetsya obobshchennyǐ modul' gladkosti i dlya nego dokazyvaetsya pryamaya i obratnaya teoremy teorii priblizheniǐ.
