Inverse theorems of approximation on the average in regions with angles

Рассматривается задача приближения в среднем функций класса $E_p$ в областях с углами. Доказывается обратная теорема приближения, которая вместе с ранее доказанной прямой теоремой позволяет сформулировать конструктивную характеристику функций класса $E_p$, удовлетворяющих обобщенному интегральному у...
