Так, совсем недавно был получен интересный результат, связывающий гамильтоновость графа с дистанционным спектральным радиусом графа, на основе которого была сформулирована более общая гипотеза о гамильтоновости графа. Мы подтверждаем выдвинутую гипотезу для k-связного графа, когда k Î{2;3}, а также устанавливаем аналогичные достаточные условия трассируемости k-связного графа, когда k Î{1; 2}.</p></abstract><trans-abstract xml:lang="en"><p>In recent years, the eigenvalues of the distance matrix of a graph have attracted a lot of attention of mathematicians, since there is a close connection between its spectrum and the structural properties of the graph. Thus, quite recently an interesting result was obtained, relating the Hamiltonicity of a graph to the distance spectral radius of the graph, on the basis of which a more general conjecture about the Hamiltonicity of a graph was formulated. We confirm this conjecture put forward for a k-connected graph, when k Î{2;3}, and also establish similar sufficient conditions for the traceability of a k-connected graph, when k Î{1; 2}.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>k-связность</kwd><kwd>гамильтоновость</kwd><kwd>трассируемость графа</kwd><kwd>дистанционная матрица графа</kwd><kwd>спектр</kwd><kwd>дистанционный спектральный радиус графа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>k-connectivity</kwd><kwd>Hamiltonicity</kwd><kwd>traceability of a graph</kwd><kwd>distance matrix of a graph</kwd><kwd>distance spectral radius of a graph</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа профинансирована Институтом математики Национальной академии наук Беларуси в рамках Государственной программы научных исследований «Конвергенция 2025».</funding-statement><funding-statement xml:lang="en">This work was funded by the Institute of Mathematics of the National Academy of Sciences of Belarus within the framework of “Convergence 2025” State Program for Scientific Research.</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">Godsil, C.
