Показано, что в конечномерных нормированных пространствах в случае, когда оба компакта являются непустыми выпуклыми подмножествами, такая операция непрерывна в топологии, порождённой метрикой Хаусдорфа.Вопрос непрерывной зависимости описанного пересечения от радиуса окрестности возник в качестве побочного продукта развития теории экстремальных сетей. Однако он оказался интересным сам по себе, предполагающим различные обобщения. Поэтому было решено опубликовать его отдельно.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we study the deformation of the intersection of one compact set with a closed neighborhood of another compact set by changing the radius of this neighborhood. It is shown that in finite–dimensional normed spaces, in the case when both compact sets are non-empty convex subsets, such an operation is continuous in the topology generated by the Hausdorff metric.The question of the continuous dependence of the described intersection on the radius of the neighborhood arose as a by–product of the development of the theory of extremal networks.However, it turned out to be interesting in itself, suggesting various generalizations. Therefore, it was decided to publish it separately.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрическая геометрия</kwd><kwd>выпуклые множества</kwd><kwd>расстояние Хаусдорфа</kwd><kwd>непрерывные деформации.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metric geometry</kwd><kwd>convex sets</kwd><kwd>Hausdorff distance</kwd><kwd>continuous deformations.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (проект No. 21-11-00355) в МГУ имени М.
