Сергей Михайлович Воронин открыл свойство универсальности дзета-функции Римана ζ(s), s = σ+it, о приближении широкого класса аналитических функций сдвигами ζ(s + iτ ), τ ∈ R. Позже оказалось, что и некоторые другие дзета-функции обладают свойством универсальности в смысле Воронина. Если сдвиг τ принимает значения из некоторого дискретного множества, то универсальность называется дискретной. В работе изучается дискретная универсальность периодических дзета-функций Гурвица. Периодическая дзета-функция Гурвица ζ(s, α; a) определяется рядом с членами am(m + α)−s, m = 0, 1, 2, . . . , где 0 &lt; α ≤ 1 – фиксированное число, а a = {am} – периодическая последовательность комплексных чисел. Доказано, что широкий класс аналитических функций с заданной точностью приближается сдвигами ζ(s + ihkβ1 logβ2 k, α; a) с k = 2, 3, . . . , где h &gt; 0 и 0 &lt; β1 &lt; 1, β2 &gt; 0 – фиксированные числа, а множество {log(m + α) : m = 0, 1, 2, . . . } линейно независимо над полем рациональных чисел. Получено, что множество таких сдвигов, приближающих данную аналитическую функцию, имеет положительную нижнюю плотность. При доказательстве используются свойства равномерно распределенных по модулю 1 последовательностей действительных чисел.</p></abstract><trans-abstract xml:lang="en"><p>In 1975, Sergei Mikhailovich Voronin discovered the universality of the Riemann zetafunction ζ(s), s = σ + it , on the approximation of a wide class of analytic functions by shifts ζ(s + iτ ), τ ∈ R. Later, it turned out that also some other zeta-functions are universal in the Voronin sense. If τ takes values from a certain descrete set, then the universality is called discrete. In the present paper, the discrete universality of periodic Hurwitz zeta-functions is considered. The periodic Hurwitz zeta-function ζ(s, α; a) is defined by the series with terms am(m + α)−s, where 0 &lt; α ≤ 1 is a fixed number, and a = {am} is a periodic sequence of complex numbers. It is proved that a wide class of analytic functions can be approximated by shifts ζ(s+ihkβ1 logβ2 k, α; a) with k = 2, 3, ..., where h &gt; 0 and 0 &lt; β1 &lt; 1, β2 &gt; 0 are fixed numbers, and the set {log(m+α) : m = 0, 1, 2} is linearly independent over the field of rational numbers. It is obtained that the set of such k has a positive lower density. For the proof, properties of uniformly distributed modulo 1 sequences of real numbers are applied.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>периодическая дзета-функция Гурвица</kwd><kwd>предельная теорема</kwd><kwd>пространство аналитических функций</kwd><kwd>универсальность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>periodic Hurwitz zeta-function</kwd><kwd>space of analytic functions</kwd><kwd>limit theorem</kwd><kwd>universality.</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">Billingsley P.
