В основу положен метод В. Блиновского: 1) выводится выражение для функции $L(\sigma,a)$ – квадрата модуля основной части дзета-функции, влияющей на ее нули, 2) доказательство гипотезы Римана сводится к доказательству выпуклости вниз функции $L$ по $\sigma,$ т. е. положительности $L_{\sigma\sigma}^{(2)}(\sigma,a).$ Авторами показаны оценки, позволяющие описать область $\Theta_R,$ приведены данные вычислительного эксперимента, проведенного в математическом пакете Maxima, по построению области $\Theta_R.$ Сделан обзор литературы по современному состоянию вопроса доказательства гипотезы. Предложено дальнейшее развитие метода как с точки зрения расширения области $\Theta_R,$ так и для повышения вычислительной эффективности.</p></abstract><trans-abstract xml:lang="en"><p>The authors of this article prove the Riemann hypothesis for a special case when the real $\sigma$ and imaginary $T=1/(2a)$ parts of the zeta function argument belong to a certain region $\Theta_R$ of the complex plane. It is based on V. Blinovsky's method: 1) an expression is derived for the function $L(\sigma,a),$ the square of the modulus of the fundamental part of the zeta function, which affects its zeros, 2) the proof of the Riemann hypothesis is reduced to proving the U-convexity of the function $L$ by $\sigma,$ i. e. the positivity of $L_{\sigma\sigma}^{(2)}(\sigma,a).$ The authors provide estimates that allow us to describe the region $\Theta_R,$ and present the data of a computational experiment conducted in the Maxima mathematical package by constructing the region $\Theta_R.$ A literature review on the current state of hypothesis proof is provided. Further development of the method is proposed both in terms of expanding the region $\Theta_R$ and for increasing computational efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипотеза Римана</kwd><kwd>метод Блиновского</kwd><kwd>дзета-функция</kwd><kwd>гамма-функция</kwd><kwd>математический пакет Maxima</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Riemann hypothesis</kwd><kwd>Blinovsky’s method</kwd><kwd>zeta function</kwd><kwd>gamma function</kwd><kwd>Maxima mathematical package</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">И.
