Рассматриваются два типа сдвигов: непрерывный и дискретный.</p><p>В работе изучается универсальность дзета-функций Лерха L(λ,α,s), s = σ + it, которые в полуплоскости σ &gt; 1 определяются рядами Дирихле с членами e2πiλm(m + α)−s с фиксированными параметрами λ ∈ R и α, 0 &lt; α ≤ 1, и мероморфно продолжаются на всю комплексную плоскость. Получены совместные дискретные теоремы универсальности для дзета-функций Лерха. Именно, набор аналитических функций f1(s),...,fr(s) одновременно приближаются сдвигами L(λ1,α1,s + ikh),...,L(λr,αr,s + ikh), k = 0,1,2,..., где h &gt; 0 - фиксированное число. При этом требуется линейная независимость над полем рациональных чисел множества{(log(m + αj) : m ∈N0, j = 1,...,r), }. Доказательство теорем универсальности использует вероятностные предельные теоремы о слабой сходимости вероятностных мер в пространстве аналитических функций.</p></abstract><trans-abstract xml:lang="en"><p>After Voronin’s work of 1975, it is known that some of zeta and L-functions are universal in the sense that their shifts approximate a wide class of analytic functions. Two cases of shifts, continuous and discrete, are considered.</p><p>The present paper is devoted to the universality of Lerch zeta-functions L(λ,α,s), s = σ+it, which are defined, for σ &gt; 1, by the Dirichlet series with terms e2πiλm(m+α)−s with parameters λ ∈ R and α, 0 &lt; α ≤ 1, and by analytic continuation elsewhere. We obtain joint discrete universality theorems for Lerch zeta-functions. More precisely, a collection of analytic functions f1(s),...,fr(s) simultaneously is approximated by shifts L(λ1,α1,s+ikh),...,L(λr,αr,s+ikh), k = 0,1,2,..., where h &gt; 0 is a fixed number. For this, the linear independence over the field of rational numbers for the set {(log(m + αj) : m ∈N0, j = 1,...,r), [if gte msEquation 12]&gt;&lt;m:oMath&gt;&lt;i&#13;
