Given a free Abelian group 0305-4470/30/10/030/img5 of finite rank, canonical subgroup matrices 0305-4470/30/10/030/img6 are defined with respect to an arbitrary but fixed basis of 0305-4470/30/10/030/img5, which uniquely determine all subgroups 0305-4470/30/10/030/img8 of 0305-4470...
It is currently unknown whether the group E of all IETs possesses any non-abelian free subgroups. It is shown that it is not possible for a disjoint... CF Novak - 《Groups Geometry & Dynamics》 被引量: 8发表: 2010年 Abelian groups whose subgroup lattice is the union of two intervals ...
A relation module for a group H is the Abelian group ~ = 2~/R', where R is the kernel of a free presentation of H, and the H-module action on/~ is by conjugation in the free group; R is minimal if the free group involved has the same number of generators as H. Stated in ...
First we show that in any group, if the indices |X : Y| are determined for all cyclic subgroups X, then they are determined for all subgroups X. Second we show that if G is a group with an ascending normal series with factors locally finite or abelian, and if the Hirsch length of ...
