Доказывается, что для некоторых структур класс таких степеней может представляться в виде объединения нескольких верхних конусов в.п. степеней. Кроме того, будет установлено, что существуют не-в.п. верхние конусы степеней, реализующиеся классами степеней, в которых вычислимая структура относительно вычислимо категорична.</p></abstract><trans-abstract xml:lang="en"><p>We study the classes of Turing degrees of selector functions in which a rigid computable structure is relatively computably categorical. It is proved that for some structures such classes of degrees can be represented as the unions of upper cones of c.e. degrees. In addition we show that there are non-c.e. upper cones realized as the degrees in which some computable structure is relatively computably categorical.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вычислимо перечислимые (в.п.) множества</kwd><kwd>n-в.п. множества</kwd><kwd>тьюринговые степени</kwd><kwd>вычислимые алгебраические структуры</kwd><kwd>относительнная вычислимая категоричность</kwd><kwd>селекторные функции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computably enumerable (c.e.) sets</kwd><kwd>n-c.e. sets</kwd><kwd>Turing degrees</kwd><kwd>computable alebrai structures</kwd><kwd>relative computable categoricity</kwd><kwd>selector functions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Фондом развития теоретической физики и математики “БАЗИС”.</funding-statement><funding-statement xml:lang="en">The work was supported by the Theoretical Physics and Mathematics Advancement Foundation “BASIS”</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">C.
