Действительно, работ по о-минимальным частично упорядоченным структурам очень и очень мало. Стандартное определение о-минимальности для частично упорядоченных структур говорит, что любое формульное подмножество представимо в виде булевой комбинации интервалов и точек. Поскольку булева комбинация включает операцию взятия дополнения множества, а в частично упорядоченных множествах дополнение интервала может быть устроено чрезвычайно сложно, есть определенные сложности в исследовании таким образом определенного класса структур. Мы предлагаем использовать другое определение о-минимальности – частично упорядоченная структура является о-минимальной, если любое ее формульное подмножество является конечным объединением обобщенных интервалов и точек. В статье мы приводим ряд примеров, которые показывают, что данное определение нетривиально, что есть структуры, которые являются о-минимальными в новом смысле.</p></abstract><trans-abstract xml:lang="en"><p>The notion of o-minimality is highly productive for linearly ordered structures, but a direct transfer of this concept to partially ordered sets encounters certain difficulties. Indeed, there is a striking scarcity of works on o-minimal partially ordered structures. The standard definition of o-minimality for partially ordered structures states that every definable subset is a Boolean combination of intervals and points. However, since Boolean combinations involve the operation of taking set complements, and in partially ordered sets the complement of an interval can be extremely complex, this approach presents certain challenges for studying the resulting class of structures. We propose using an alternative definition of o-minimality: a partially ordered structure is o-minimal if every definable subset is a finite union of generalized intervals and points. In the paper, we provide a number of examples demonstrating that this definition is nontrivial and that there exist structures which are o-minimal in this new sense.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>частично упорядоченное множество</kwd><kwd>о-минимальность</kwd><kwd>выпуклое множество</kwd><kwd>сильно минимальная структура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>partially ordered set</kwd><kwd>o-minimality</kwd><kwd>convex set</kwd><kwd>strongly minimal structure</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данные исследования поддержаны Комитетом науки Министерства науки и высшего образования Республики Казахстан (грант BR20281002).</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">Dauletiyarova A.
