Полевые переменные модели в этом случае задают серию топологических отображений Хопфа φ : R4n–1 → S2n, с обычным вакуумным граничным условием φ(x) → φ0 при |x| →∞ Соответствующие солитонные конфигурации классифицируются инвариантом Q, обобщающим первый инвариант Хопфа при отображении S3 → S2. Показано существование топологического ограничения на величину энергии регулярных полевых конфигураций 1 , E ≥ c|Q|d/d+1обобщающего неравенство Вакуленко–Капитанского.</p></abstract><trans-abstract xml:lang="en"><p>We discuss the possibility of constructing topological solitons which generalize the Hopfian field configurations in the scalar Faddeev–Skyrme model extended to the case of spaces with the dimensions d = 4n – 1, nєZ. The fields of the model are the Hopf maps φ : R4n–1 → S2n with the usual vacuum boundary condition φ(x) → φ0 as x →∞. These soliton configurations are labelled by the topological invariant Q, which generalizes the first Hopf invariant of the map S3 → S2. We have demonstrated that there is a topological energy bound E ≥ c|Q|d⁄d+1, which generalizes the Vaculenko–Kapitansky inequality.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Skyrme T.
