Also a formula for the Mehler–Fock transform of the Legendre function of an inverse argument is obtained. Moreover, a generalization of one known formula for the Mehler–Fock transform is derived.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>преобразование Бушмана — Эрдейи</kwd><kwd>преобразование Мелера–Фока</kwd><kwd>функция Лежандра.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Buschman–Erdelyi transform</kwd><kwd>Mehler–Fock transform</kwd><kwd>Legendre function.</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">Градштейн И.
