Для некоторых классов двудольных графов вычислено минимальное число самопересечения для всех двудольных погружений. В частности описаны все графы, обладающие двудольным вложением в плоскость. Даны приложения к хронологическому упорядочению начального чекана Ширваншаха Абу Мансур Али ибн Йазида (425–435 гг.х. = 1034–1044 р.х.).</p></abstract><trans-abstract xml:lang="en"><p>Bipartite immersions of a bipartite graph into a plane with a minimum self-intersection number are studied. For some classes of bipartite graphs, the minimum self-intersection number is calculated for all bipartite immersions. In particular, all graphs with a bipartite embeddinginto a plane are described. Appendixes are given to the chronological ordering of the initial coinage of Shirvanshah Abu Mansur Ali bin Yazid (425-435 AH = 1034-1044 AD).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конечнократное отображение в евклидово пространство</kwd><kwd>размерность</kwd><kwd>плотное подмножество.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>finite-multiple mapping into Euclidean space</kwd><kwd>dimension</kwd><kwd>dense subset.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Thomassen Carsten.
