Overgroups of exterior powers of an elementary group. levels
ABSTRACTWe prove a first part of the standard description of groups H lying between an exterior power of an elementary group mEn(R) and a general linear group GL(nm)(R) for a commutative ring R,2∈R∗ and n⩾3m. The description uses the classical notion of a level: for every group H we find …
