Предложена общая схема введения так называемой sharp-метрики на таких группах, относительно которой алгебраические операции непрерывны и которая является неархимедовой. Показано, что такая группа всюду плотно вкладывается в полную группу, элементами которой являются ряды специального вида из элементов $L$. Аналогичные конструкции рассмотрены для градуированных колец и градуированных векторных пространств. В качестве примеров показано, что в конкретных частных случаях применение описанной конструкции приводит к построению $p$-адических чисел и  к построению рядов Тейлора и Лорана.</p></abstract><trans-abstract xml:lang="en"><p>A group $L$ is called graded if it is represented as the union of a decreasing sequence of subgroups $L_m$. A general scheme for introducing the so-called sharp metric on such groups is proposed, with respect to which the algebraic operations are continuous and which is non-archimedean. It is shown that such a group is densely embedded in a complete group whose elements are series of a special type composed of elements of $L$. Similar constructions are considered for graded rings and graded vector spaces. As examples, it is shown that in concrete special cases, the application of the described construction leads to the construction of $p$-adic numbers and to the construction of Taylor and Laurent series.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>градуированное множество</kwd><kwd>неархимедова метрика</kwd><kwd>sharp-топология</kwd><kwd>градуированная группа</kwd><kwd>градуированное векторное пространство</kwd><kwd>$p$-адический анализ</kwd><kwd>полином Тейлора</kwd><kwd>асимптотическая сходимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>graded set</kwd><kwd>non-archimedean metric</kwd><kwd>sharp topology</kwd><kwd>graded group</kwd><kwd>graded vector space</kwd><kwd>$p$-adic analysis</kwd><kwd>Taylor polynomial</kwd><kwd>asymptotic convergence.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бурбаки Н.
