В работе устанавливаются достаточные условия существования совершенного паросочетания в K1,p -ограниченных графах. Из этих условий, в частности, вытекает классический результат Ю. Петерсена о том, что в любом реберно 2-связном 3-регулярном графе существует совершенное паросочетание.</p></abstract><trans-abstract xml:lang="en"><p>A graph is called K1,p-restricted (p ≥ 3) if for every vertex of the graph there are at least p - 2 edges between any p neighbours of the vertex. In this article, new sufficient conditions for existence of a perfect matching in K1,p-restricted graphs are established. In particular, J. Petersen’s classical result that every 2-edge connected 3-regular graph contains a perfect matching follows from these conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>K1</kwd><kwd>p-ограниченный граф</kwd><kwd>сильно K1</kwd><kwd>p-ограниченный граф</kwd><kwd>совершенное паросочетание</kwd><kwd>факторно-критический граф</kwd></kwd-group><kwd-group xml:lang="en"><kwd>K1</kwd><kwd>p-restricted graph</kwd><kwd>strongly K1</kwd><kwd>p-restricted graph</kwd><kwd>perfect matching</kwd><kwd>factor-critical graph</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">Ловас, Л.
