Найдены все 5-мерные подалгебры 6-мерных нильпотентных алгебр Ли над полем характеристики нуль. Как известно, с точностью до изоморфизма, все 6-мерные нильпотентные алгебры Ли были получены ранее В. В. Морозовым, их число равно 32. Однако стандартный метод, основанный на формуле Кэмпбелла – Хаусдорфа, оказался неэффективным для нахождения подалгебр алгебр Ли размерности 5 и выше. Вместо этого для нахождения 5-мерных подалгебр перечисленных 6-мерных нильпотентных алгебр Ли использован новый метод – канонические базисы.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we consider the classical problem of the classification of subalgebras of small dimensional Lie algebras. We found all 5-dimentional subalgebras of 6-dimentional nilpotent Lie algebras under the field with the zero characteristic. As is known, up to isomorphism all 6-dimensional nilpotent Lie algebras (their number is 32) were received by V. V. Morosov. However, the standard method based on the Campbell – Hausdorf formula is not effective for the determination of subalgebras of Lie 5- or higher dimensional algebras. In our research, we use a new approach to the solution of the problem of the determination of 5-dimensional subalgeras of indicated 6-dimensional nilpotent Lie algerbas, namely, the application of canonical bases for subspaces of vector spaces.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нильпотентные алгебры Ли</kwd><kwd>подалгебры</kwd><kwd>канонические базисы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nilpotent Lie algebras</kwd><kwd>subalgebras</kwd><kwd>canonical bases</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">Patera, J.
