Впервые это описание появилось в работе Дж. Маклафлина, которая была одной из первых в изучении порождений длинными корневыми унипотентными подгруппами в группах Шевалле. На данный момент геометрия длинных корневых унипотентных подгрупп хорошо изучена. Но остаётся много нерешённых вопросов, связанных с порождениями короткими корневыми унипотентными подгруппами. В частности, неизвестно описание неприводимых подгрупп, порождённых короткими корневыми подгруппами, в исключительных группах Шевалле над произвольным полем. В приводимом доказательстве мы рассматриваем группу SL(𝑛,𝐾) как группу Шевалле типа Aℓ. Таким образом, по мнению авторов, предложенный подход можно перенести на описание неприводимых подгрупп, порождённых короткими корневыми унипотентными подгруппами, в группах Шевалле.</p></abstract><trans-abstract xml:lang="en"><p>In the present paper we give a new proof of the description of irreducible subgroups generated by root subgroups in special linear group SL(𝑛,𝐾). For the first time such a description wasappeared in J. McLaughlin’s work. His work was one of the first papers dedicated to study of the generations by long root unipotent subgroups in Chevalley groups. At the present time the geometry of long root subgroups is a well-established field. But it remains a lot of unsolved tasks about short root unipotent subgroups. In particular, the description of irreducible subgroupsgenerated by short root subgroups in exceptional Chevalley groups over arbitrary field is unknown. In our proof we consider the group SL(𝑛,𝐾) as the Chevalley group of type Aℓ. Thusin our opinion it is possible to use the given approach for study of the irreducible subgroups generated by short root subgroups in Chevalley groups.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полная линейная группа</kwd><kwd>специальная линейная группа</kwd><kwd>унипотентные корневые подгруппы</kwd><kwd>неприводимые подгруппы.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>general linear group</kwd><kwd>special linear group</kwd><kwd>unipotent root subgroups</kwd><kwd>irreducible subgroups.</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">Вавилов Н.
