Abstract

В работе исследуется задача об описании сл едов функций из изотропны х полунормированных пространств типа Соб олева в терминах полунормированных п ространств типа прос транств Бесова.

Полученное описание приn=2 носит характер необходимых и достат очных условий. Оно отличается от соо тветствующих резуль татов для анизотропных простр анств.
