Классическим утверждением здесь является теорема об интегрируемости произведения интегрируемой функции и функции ограниченной вариации. Приводится несколько более общих утверждений для функций, одна из которых имеет первообразную, удовлетворяющую обычному или обобщенному условию Гельдера с показателем α или модулем φ, а вторая – сама удовлетворяет обычному или обобщенному условию Гельдера, соответственно с показателем β или модулем ψ, причем α + β &gt; 1 или функция t–2φ(t)ψ(t) интегрируема в окрестности нуля. Аналогичные утверждения установлены и для функций с ограниченными вариациями в смысле Винера, Янга, Уотермана и Шрама.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the problem of integrability of the product of integrable functions in the Kurzweil–Henstock sense. The classical theorem states here that the product of an integrable function and a function of bounded variation is also integrable. In the article it is proved that the product of a function with the primitive satisfying the Hölder condition with the exponent α or with the module φ and a function satisfying the Hölder condition with the exponent β or with the module ψ such that α + β &gt; 1  or t–2φ(t)ψ(t) is integrable. Similar results for functions with generalized (Winer, Young, Waterman, Schramm) bounded variations are stated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интегралы Римана</kwd><kwd>Лебега</kwd><kwd>Курцвейля–Хенстока</kwd><kwd>интеграл Римана–Стильтьеса</kwd><kwd>функции ограниченной вариации</kwd><kwd>обобщенные вариации функций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Riemann</kwd><kwd>Lebesgue</kwd><kwd>Kurzweil–Henstock integrals</kwd><kwd>Riemann–Stiltjes integral</kwd><kwd>functions of bounded variation</kwd><kwd>generalized variations of functions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лукомский, С.
