На самом деле мы показываем формулу точного остатка для этих результатов. В частности, наше тождество подразумевает соответствующие неравенства Харди и критические неравенства Харди с любой однородной квазинормой для оператора радиальной производной, что дает улучшенные версии соответствующих классических аналогов. Более того, мы обсуждаем расширение этих результатов в контексте однородных групп Ли Фолланда и Штейна. Такая более общая постановка удобна для обобщения результатов гармонического анализа, зависящих только от групповой и расширяющих структур, что является одной из наших мотиваций при работе в этой среде. Наш подход основан на методе факторизации дифференциальных операторов, предложенном Гестези и Литтлджоном. В качестве приложения мы показываем неравенства типа Каффарелли-Кона-Ниренберга с более общим весом. Благодаря свободе выбора с любой однородной квазинормы наши результаты уже дают значительные преимущества, так как они применимы как к анизотропному пространству ℝn , так и к изотропному пространству ℝn.</p></abstract><trans-abstract xml:lang="en"><p>In this note we obtain Hardy and critical Hardy inequalities with any homogeneous quasi-norm in unified way. Actually, we show a sharp remainder formula for these results. In particular, our identity implies corresponding Hardy and critical Hardy inequalities with any homogeneous quasi-norm for the radial derivative operator, thus yielding improved versions of corresponding classical counterparts. Moreover, we discuss extensions of these results in the setting of Folland and Stein’s homogeneous Lie groups. Such a more general setting is convenient for the distillation of those results of harmonic analysis depending only on the group and dilation structures, which is one of our motivations working in the setting. Our approach based on the factorization method of differential operators introduced by Gesztesy and Littlejohn. As an application, we show Caffarelli-Kohn-Nirenberg type inequalities with more general weight. Because of the freedom in the choice of any homogeneous quasi-norm, our results give new insights already in both anisotropic ℝn and isotropic ℝn . </p></trans-abstract><kwd-group xml:lang="ru"><kwd>метод факторизации</kwd><kwd>неравенство Харди</kwd><kwd>однородная группа Ли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>factorization method</kwd><kwd>Hardy inequality</kwd><kwd>homogeneous Lie group</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research is funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. AP14871691).</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">Balinsky A.A., Evans W.D., Lewis, R.T.
