Гилберту. В 1990, выступая с докладом на Международном конгресе математиков в Париже, он выдвинул гипотезу, что дзета-функция Римана не удовлетворяет никакому алгебраическому дифференциальному уравнению. Эта гипотеза была доказана А. Островским. В 1975 г. С.М. Воронин доказал функциональную независимость дзета-функции Римана. С тех пор многими авторами была получена функциональная независимость ряда дзета и L-функций. В настоячей статье получена совместная функциональная независимость дзета-функции Римана и периодических дзета-функциий Гурвица с параметрами, алгебраически независимыми над полем рациональных чисел. Такая функциональная независимость иногда называется смешанной, поскольку дзета-функция Римана имеет эйлеровое произведение по простым числам, а периодические дзета-функции Гурвица такого произведения не имеет.</p></abstract><trans-abstract xml:lang="en"><p>The functional independence of zeta-functions is an interesting nowadays problem. This problem comes back to D. Hilbert. In 1900, at the International Congress of Mathematicians in Paris, he conjectured that the Riemman zeta-function does not satisfy any algebraicdifferential equation. This conjecture was solved by A. Ostrowski. In 1975, S.M. Voronin proved the functional independence of the Riemann zeta-function. After that many mathematicians obtained the functional independence of certain zeta- and L-functions. In the present paper, the joint functional independence of a collection consisting of the Riemann zeta-function and several periodic Hurwitz zeta-functions with parameters algebraically independent over the field of rational numbers is obtained. Such type of functional independence is called as “mixed functional independence” since the Riemann zeta-function has Euler product expansion over primes while the periodic Hurwitz zeta-functions do not have Euler product.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дзета-функция Римана</kwd><kwd>дзета-функция Гурвица</kwd><kwd>периодические коэффициенты</kwd><kwd>функциональная независимость</kwd><kwd>универсальность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functional independence</kwd><kwd>Hurwitz zeta-function</kwd><kwd>periodic coefficients</kwd><kwd>Riemann zeta-function</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">H¨older O. ¨Uber die Eigenschaft der Gamafunktion keiner algebraischen Differentialgleichung zu genugen // Math.
