Рассматривается как классическое определение вычислимой нумерации семейства вычислимых функций, согласно которому по номеру функции в этой нумерации эффективно определяется ее геделевский номер, так и расширяющее предыдущее определение, основанное на равномерном применении понятия вычислимо перечислимого слева элемента бэровского пространства. Основной вопрос, исследуемый в статье, заключается в возможности порождения всех вычислимых нумераций семейства замыканием относительно сводимости бесконечных прямых сумм равномерных последовательностей его однозначных, позитивных и минимальных нумераций.</p></abstract><trans-abstract xml:lang="en"><p>The paper discusses two approaches to defining the computability of numberings of families of total functions. We consider both the classical definition of computable numbering of a family of computable functions, according to which the number of a function in this numbering effectively provides its G\"odel number, and, expanding the previous one, a definition based on the uniform application of the concept of the left-c.e. element of Baire space. The main question studied in the paper is the possibility of generating all computable numberings of a family by the closure with respect to the reducibility of infinite direct sums of uniform sequences of its single-valued, positive, and minimal numberings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вычислимая нумерация</kwd><kwd>однозначная нумерация</kwd><kwd>позитивная нумерация</kwd><kwd>минимальная нумерация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computable numbering</kwd><kwd>single-valued numbering</kwd><kwd>positive numbering</kwd><kwd>minimal numbering</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом Российского научного фонда (проект 23-21-00181) и выполнена в рамках реализации программы развития Научно-образовательного математического центра Приволжского федерального округа (соглашение 075-02-2023-944)</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">Friedberg R.
