Мы используем для частичных порядков такие характеристики, как высота структуры, означающая супремум длин упорядоченных цепей, и ширина структуры, означающая супремум длин антицепей, где антицепь – это множество попарно несравнимых элементов. Мы также различаем как тривиальную ширину, так и нетривиальную ширину. Недавно Кулпешов Б.Ш, Павлюк Ин.И. и Судоплатов С.В. описали сильно минимальные частичные порядки, имеющие конечную нетривиальную ширину. Здесь мы исследуем сильно минимальные частичные порядки, имеющие бесконечную нетривиальную ширину. Основной результат статьи – критерий сильной минимальности бесконечного частичного порядка высоты два, имеющие бесконечную нетривиальную ширину</p></abstract><trans-abstract xml:lang="en"><p>In the present paper, we study strongly minimal partial orderings in the signature containing only the symbol of binary relation of partial order. We use for partial orderings such characteristics as the height of a structure that is the supremum of lengths of ordered chains, and the width of a structure that is the supremum of lengths of antichains, where an antichain is a set of pairwise incomparable elements. We also differ trivial width and non-trivial width. Recently, B.Sh. Kulpeshov, In.I. Pavlyuk and S.V. Sudoplatov described strongly minimal partial orderings having a finite non-trivial width. Here we study strongly minimal partial orderings having an infinite non-trivial width. The main result of the paper is a criterion for strong minimality of an infinite partial ordering of height two having an infinite non-trivial width.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сильно минимальная структура</kwd><kwd>частичный порядок</kwd><kwd>связная компонента</kwd><kwd>максимальный элемент</kwd><kwd>минимальный элемент.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>strongly minimal structure</kwd><kwd>partial ordering</kwd><kwd>connected component</kwd><kwd>maximal element</kwd><kwd>minimal element</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>The work was supported by Science Committee of Ministry of Science and Higher Education of the Republic of Kazakhstan, grants BR20281002 and AP19674850.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was supported by Science Committee of Ministry of Science and Higher Education of the Republic of Kazakhstan, grants BR20281002 and AP19674850.</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">Baldwin J.T., Lachlan A.H.
