Пусть \(\pi:X\to C\) -- сюръективный морфизм гладких проективных многообразий над конечным полем \(F_q\) характеристики \(p\), \(C\) -- кривая, общий схемный слой морфизма \(\pi\) является гладким многообразием \(V\) над полем \(k=\kappa(C)\) рациональных функций кривой \(C\), \(\overline k\) -- алгебраическое замыкание поля \(k\), \(k^s\) -- его сепарабельное замыкание, \(NS(V)\) -- группа Нерона -- Севери классов дивизоров на многообразии \(V\) по модулю алгебраической эквивалентности, причем выполнены следующие условия: \(H^1(V\otimes\overline k,\mathcal O_{V\otimes\,\overline k})=0,\) \; \(NS(V)=NS(V\otimes\overline k).\) Если для простого числа \(l\), не делящего \({Card}([NS(V)]_{tors})\) и отличного от характеристики поля \(F_q\), верно соотношение \(NS(V)\otimes\Bbb Q_l\,\,\widetilde{\rightarrow}\,\,[H^2(V\otimes k^{sep},Q_l(1))]^{Gal( k^{sep}/k)} \)\; \((\)другими словами, если верна гипотеза Тэйта для дивизоров на \(V )\), то для любого простого числа \(l\neq charr(F_q)\) гипотеза Тэйта верна для дивизоров на \(X\): \(NS(X)\otimes Q_l\,\,\widetilde{\rightarrow} \,\,[H^2(X\otimes\overline F_q,Q_l(1))]^{Gal(\overline F_q/ F_q)}.\) В частности, из этого результата следует гипотеза Тэйта для дивизоров на арифметической модели K3 -- поверхности над достаточно большим глобальным полем конечной характеристики, отличной от 2.</p></abstract><trans-abstract xml:lang="en"><p>We investigate interrelations between the Tate conjecture for divisors on a fibred variety over a finite field and the Tate conjecture for divisors on the generic scheme fibre under the condition that the generic scheme fibre has zero irregularity. Let \(\pi:X\to C\) be a surjective morphism of smooth projective varieties over a finite field \(F_q\) of characteristic \(p\), \(C\) is a curve and the generic scheme fibre of \(\pi\) is a smooth variety \(V\) over the field \(k=\kappa(C)\) of rational functions of the curve \(C\), \(\overline k\) is an algebraic closure of the field \(k\), \(k^s\) is its separable closure, \(NS(V)\) is the N\'eron - Severi group of classes of divisors on the variety \(V\) modulo algebraic equivalence, and assume that the following conditions hold: \(H^1(V\otimes\overline k,\mathcal O_{V\otimes\,\overline k})=0,\) \(NS(V)=NS(V\otimes\overline k).\) If, for a prime number \(l\) not dividing \({Card}([NS(V)]_{tors})\) and different from the characteristic of the field \(F_q\), the following relation holds \(NS(V)\otimes\Bbb Q_l\,\,\widetilde{\rightarrow}\,\,[H^2(V\otimes k^{sep},Q_l(1))]^{Gal( k^{sep}/k)} \) \((\)in other words, if the Tate conjecture for divisors on \(V\) holds\()\), then for any prime number \(l\neq charr(F_q)\) the Tate conjecture holds for divisors on \(X\): \(NS(X)\otimes Q_l\,\,\widetilde{\rightarrow} \,\,[H^2(X\otimes\overline F_q,Q_l(1))]^{Gal(\overline F_q/F_q)}.\) In  particular, it follows from this result that the Tate conjecture for divisors on an arithmetic model of a \(K3\) surface over a sufficiently large global field of finite characteristic different from 2 holds as well.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипотеза Тэйта</kwd><kwd>глобальное поле</kwd><kwd>группа Брауэра</kwd><kwd>арифметическая модель</kwd><kwd>K3 – поверхность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Tate conjecture</kwd><kwd>global ﬁeld</kwd><kwd>Brauer group</kwd><kwd>arithmetic model</kwd><kwd>K 3 surface</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">J.S.
