Оценено, количество натуральных чисел, которые нельзя представить в указанном виде, т.е. исключительное множество задачи. Также впервые получена оценка снизу для количества представлений данного не исключительного 𝑛 в указанном виде.</p></abstract><trans-abstract xml:lang="en"><p>The work studies the problem of representing the natural number 𝑛 as the sum of the squaresof four prime numbers from an arithmetic progression. The number of natural numbers thatcannot be represented in the specified form has been estimated, i.e. the exceptional set of theproblem, is estimated.. Also, for the first time, a lower estimate was obtained for the numberof representations of a given non-exceptional 𝑛 in the indicated form.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диофантово уравнение</kwd><kwd>конгруэнтразрешимость</kwd><kwd>положительная разрешимость</kwd><kwd>исключительный нуль</kwd><kwd>𝐿-функция Дирихле</kwd><kwd>символ Лежандра</kwd><kwd>малая дуга</kwd><kwd>большая дуга</kwd><kwd>особый ряд</kwd><kwd>особый интеграл.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diophantine equation</kwd><kwd>congruent solution</kwd><kwd>positive solution</kwd><kwd>exceptional zero</kwd><kwd>Dirichlet 𝐿-function</kwd><kwd>Legendre symbol</kwd><kwd>minor arc</kwd><kwd>major arc</kwd><kwd>singular series</kwd><kwd>singular integral.</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">Нестеренко, Ю.В.
