A Characterization of Cyclic Groups via Indices of Maximal Subgroups


A Characterization of Cyclic Groups via Indices of Maximal Subgroups

It's less well known that the same property characterizes the infinite cyclic group: if distinct subgroups of an infinite group have distinct indices (as ...

(PDF) A Characterization of the Cyclic Groups by Subgroup Indices

In this paper, we prove that an arbitrary group G is cyclic if and only if distinct subgroups of G have distinct indexes in G.

Characterizing maximal subgroups of cyclic groups.

As far as I see, there are three little inaccuracies. First: You used (twice) the theorem that a subgroup of a cyclic group has to be cyclic ...

A characterization of the circle group via uniqueness of roots

We show then that an infinite compact abelian group G has all its cyclic subgroups g- closed iff G ∼= T. © 2010 Elsevier B.V. All rights reserved. 1.

On a characterization of infinite cyclic groups

The group G, being solvable, contains a maximal normal subgroup M of prime index, say q. Its preimage M is, by induction assumption, cyclic and normal in G. Let ...

Finite groups with all maximal subgroups isomorphic

The finite groups that have a unique maximal subgroup are exactly the cyclic groups of prime power order, Z/pnZ - these are the simplest ...

The Theory of p-Groups

Proof: Firstly notice that every maximal subgroup of a p-group is normal, and of index p. This means that if M is a maximal subgroup of G, then G/M is cyclic of ...

subgroups of gl2(f

Definition 8.1. For G a finite group, a maximal cyclic subgroup is a subgroup H ⊂ G (possibly equal to G) which is cyclic and is not.

Supersolubility and some Characterizations of Finite ... - Chris Pinnock

It follows from 1.7 that maximal subgroups exist in non-trivial supersoluble groups. A subgroup of prime index is clearly maximal. In a supersoluble group, the ...

Finite groups with few conjugacy classes of maximal subgroups

A nontrivial solvable group always has a maximal subgroup which is normal and of prime index, so either M or L is normal in G. If only one of ...

A characterization of hypercyclically embedded subgroups using ...

Abstract. A normal subgroup K of a finite group G is said to be hypercyclically embedded in G if every chief factor of G below K is cyclic.

The next result is almost the only property shared by all CG- groups. Lemma 2. If G is a CG-group, every maximal subgroup of G has countable index. Proof. Let M ...
