Доказательство будет использовать некоторые свойства целочисленных решеток. Будем последовательные натуральные числа представлять в виде суммы квадратов целых чисел, стремясь к тому, чтобы в указанных представлениях было как можно меньше слагаемых. Можно убедиться, что из первых пятнадцати натуральных чисел только числа 7 и 15 представляются  в виде суммы четырех квадратов целых чисел, остальные могут быть представлены в виде суммы менее чем четырех квадратов целых чисел.</p></abstract><trans-abstract xml:lang="en"><p>The article examined as the theoretician-Lagrange's four-squares theorem follows from the geometric Minkowski theorem on a convex body. The proof will use some properties of integer lattices. We will represent consecutive natural numbers in the form of a sum of squares of integers, trying to ensure that in these representations there are as few terms as possible. It can be verified that of the first fifteen natural numbers, only the numbers 7 and 15 are represented as the sum of four squares of integers, the rest can be represented as the sum of less than four squares of integers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теорема Лагранжа</kwd><kwd>теорема Минковского</kwd><kwd>произвольный вектор</kwd><kwd>целые точки</kwd><kwd>проблема Варинга</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Lagrange theorem</kwd><kwd>Minkowski theorem</kwd><kwd>arbitrary vector</kwd><kwd>integer points</kwd><kwd>Waring's problem</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">Belousov E.G.
