Оставался нерешенным вопрос о том, что существует ли бесконечное семейство всюду определенных функций с гипериммунно-свободным оракулом А, которое имеет -вычислимую главную нумерацию. В работе приводится положительный ответ на указанный вопрос: доказано, что существует бесконечное -вычислимое семейство F всюду определенных функций, где тьюрингова степень множества A гипериммунно-свободна, такое, что F имеет A-вычислимую главную нумерацию.</p></abstract><trans-abstract xml:lang="en"><p>It was known that any non-single-element (in particular, any infinite) family of total functions with an oracle A, such that Ø′≤TA, does not have A-computable principal numbering; later it was proved that any finite family of total functions with a hyperimmune-free oracle A always has an A-computable principal numbering. The unresolved question was whether there exists an infinite family of total functions with a hyperimmune-free oracle A that has an A-computable principal numbering. The paper gives a positive answer to this question: it is proved that there exists an infinite A-computable family F of total functions, where the Turing degree of the set A is hyperimmune-free, such that F has an A-computable principal numbering.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>A-вычислимая нумерация</kwd><kwd>гипериммунный оракул</kwd><kwd>гипериммунно-свободный оракул</kwd><kwd>главная нумерация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>A-computable numbering</kwd><kwd>hyperimmune oracle</kwd><kwd>hyperimmune-free oracle</kwd><kwd>principal numbering</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This work was supported by the Science Committee of the Republic of Kazakhstan (Grant AP08856493).</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">Yu.L.
