A note on the approximation by a sum of two algebras

Aida Asgarova, Vugar Ismailov

We consider the problem of approximation of a continuous function $f$ defined on a compact metric space $X$ by elements from a sum of two algebras. We prove a de la Vallée Poussin…

A Chebyshev type alternation theorem for best approximation by a sum of two algebras

Aida Asgarova, Ali Huseynli, Vugar Ismailov

Let $X$ be a compact metric space, $C (X)$ be the space of continuous real-valued functions on $X$ , and $A_{1}$ , $A_{2}$ be two closed subalgebras of $C (X)$ containing constant function…

On the Diliberto-Straus algorithm for the uniform approximation by a sum of two algebras

Aida Kh. Asgarova, Vugar E. Ismailov

In 1951, Diliberto and Straus proposed a levelling algorithm for the uniform approximation of a bivariate function, defined on a rectangle with sides parallel to the coordinate axe…
