Эти новые неравенства для функций являются обобщениями изопериметрических неравенств, полученных в недавней статье автора (Ф.Г. Авхадиев. Аналог метрики Пуанкаре и изопериметрические константы, Изв. вузов. Матем. (9), 92–99 (2024)).</p><p>Формулировки теорем содержат такие понятия, как область гиперболического типа, расстояние от точки до границы области, гиперболический радиус. Даны краткие схемы доказательств, в которых существенно используются метрика Пуанкаре и ее свойства, характеристики плоских областей с равномерно совершенными границами, а также пространственные области гиперболического типа в смысле Лёвнера-Ниренберга.</p></abstract><trans-abstract xml:lang="en"><p>On plane and space domains, we present several integral inequalities for functions with non-zero boundary trace. These new inequalities for functions are generalizations of the isoperimetric inequalities from the author’s recent paper (F.G. Avkhadiev. An analog of the Poincaré metric and isoperimetric constants, Russian Mathematics, 2024, Vol. 68, No. 9, pp. 79–85).</p><p>Our theorems are formulated using hyperbolic type domains, the distance from a point to the boundary of a domain and the hyperbolic radius. We give schemes of proofs using the Poincaré metric and its properties, some hyperbolic characteristics of plane domains as well as space domains of hyperbolic type in the sense of Loewner and Nirenberg.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрика Пуанкаре</kwd><kwd>расстояние до границы</kwd><kwd>гиперболический радиус</kwd><kwd>равномерно совершенное множество</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Poincaré metric</kwd><kwd>distance to the boundary</kwd><kwd>hyperbolic radius</kwd><kwd>uniformly perfect set</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Российским научным фондом, проект № 23-11-00066.</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">Авхадиев Ф.Г.
