Abstract
The result of Golubov [5, Theorem 2] on the boundedness of the Hardy-Littlewood operator
in the space BMO(ℝ) is well known. The author of the present paper solves the analogous problem in the weighted space BMO on the semi-axis ℝ+ for the operator
and also in the classical space BMO(ℝ+) for a class of integral operators involving, for example, the Riemann-Liouville fractional integral.
Реэюме
Хорошо известен результат Б.И. Голубова [5 Теорема 2] об ограниченности оператора Харди-Литтлвуда
в пространстве BMO(ℝ). Автором статьи решены аналогичные задачи в весовом пространстве BMO на полуоси ℝ+ для оператора
и в классическом пространстве BMO(ℝ+) для одного класса интегральных операторов, включаюьим, например, дробный интеграл Римана-Лиувилла.
