Для указанного класса интегралов разработан подход к квазиклассической аппроксимации, который основывается на разложении действия относительно классической траектории. В разложении действия используются только слагаемые с нулевой и второй степенью. Проводится численный анализ точности квазиклассической аппроксимации для функциональных интегралов, содержащих центробежный потенциал.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we consider the class of functional integrals with respect to the conditional Wiener measure, which is important for applications. These integrals are written using the action functional containing terms corresponding to kinetic and potential energies. For the considered class of integrals an approach to semiclassical approximation is developed. This approach is based on the decomposition of the action with respect to the classical trajectory. In the expansion of the action, only terms with degrees zero and two are used. A numerical analysis of the accuracy of the semiclassical approximation for functional integrals containing the centrifugal potential is done.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>функциональные интегралы</kwd><kwd>квазиклассическая аппроксимация</kwd><kwd>центробежный потенциал</kwd><kwd>действие</kwd><kwd>классическая траектория</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functional integrals</kwd><kwd>semiclassical approximation</kwd><kwd>centrifugal potential</kwd><kwd>action</kwd><kwd>classical trajectory</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">Feynman, R.
