Для таких рядов найдены внутренности областей сходимости, а их суммы явно выражены через суммы исходных рядов. Попутно решен вопрос об условиях изолированности нулей сумм таких рядов.</p></abstract><trans-abstract xml:lang="en"><p>Herein, taking power series from a real variable that converge on a certain interval to known sums, the authors consider the power series with the same coefficients from an h-complex variable. For such series, the interiors of the regions of convergence are found, and their sums are explicitly expressed in terms of the sums of the original series. Along the way, the problem of isolation conditions for the zeros of the sums of such series is solved.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>степенной ряд</kwd><kwd>сумма ряда</kwd><kwd>область сходимости</kwd><kwd>кольцо h-комплексных чисел</kwd><kwd>изолированность нулей функции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>power series</kwd><kwd>sum of series</kwd><kwd>area of convergence</kwd><kwd>ring of h-complex numbers</kwd><kwd>isolation of zeros of a function</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">Antonuccio, F.
