Естественными расширениями этого пространства во многих отношениях являются пространства, введённые Суизи.Они заполняют всю шкалу между 𝐻1(R𝑑) и 𝐿10(R𝑑). В отличие от 𝐻1(R𝑑), для них известна только атомная характеризация. Для оценок операторов Хаусдорфа на 𝐻1(R𝑑) всегда применялись и другие характеризации. Поскольку эта возможность исключена для пространств Суизи, в настоящей статье разработан подход к оценкам операторов Хаусдорфа,использующий только атомные разложения. Если на 𝐻1(R𝑑) этот подход применим для однотипных атомов, то на пространствах Суизи он не менее эффективно работает на бесконечных суммах разнородных атомов. Для одного и того же оператора Хаусдорфа условие ограниченности не зависит от пространства, а только от параметров самого оператора.Пространство же, на котором оператор действует, характеризуется выбором атомов. Приведён пример (для простоты двумерный) с матрицей растяжения аргумента только по одной переменной.</p></abstract><trans-abstract xml:lang="en"><p>During last 20 years, an essential part of the theory of Hausdorff operators is concentrated on their boundedness on the real Hardy space 𝐻1(R𝑑). The spaces introduced by Sweezy are,in many respects, natural extensions of this space. They are nested in full between 𝐻1(R𝑑) and 𝐿10 (R𝑑). Contrary to 𝐻1(R𝑑), they are subject only to atomic characterization. For the estimates of Hausdorff operators on 𝐻1(R𝑑), other characterizations have always been applied.Since this option is excluded in the case of Sweezy spaces, in this paper an approach to the estimates of Hausdorff operators is elaborated, where only atomic decompositions are used.While on 𝐻1(R𝑑) this approach is applicable to the atoms of the same type, on the Sweezy spaces the same approach is not less effective for the sums of atoms of various types. For asingle Hausdorff operator, the boundedness condition does not depend on the space but only on the parameters of the operator itself. The space on which this operator acts is characterizedby the choice of atoms. An example is given (two-dimensional, for simplicity), where a matrix dilates the argument only in one variable.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Оператор Хаусдорфа</kwd><kwd>действительное пространство Харди</kwd><kwd>атомарное разложение.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hausdorff operator</kwd><kwd>real Hardy space</kwd><kwd>atomic decomposition.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">1Второй автор был поддержан Российским научным фондом в рамках гранта № 18-11-00055 (разделы 3 и 5 принадлежат этому автору).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">W.
