Elliptically Embedded Subgroups of Polycyclic Groups
Elliptically Embedded Subgroups of Polycyclic Groups
A subgroup H of a. group G is elliptically embedded in G if for each subgroup K of G there is an integer n = n{K) such that (H, K) = HK ■ ■ ■ HK, where the product has 2n factors.It is shown that a subgroup H of a …
