Order p 2: There are just two groups, both abelian. Order p 3: There are three abelian groups, and two non-abelian groups. One of the non-abelian groups is the semidirect product of a normal cyclic subgroup of order p 2 by a cyclic group of order p. The other is the quaternion group for p = 2 and a group of exponent p for p > 2.
Abelians (Latin: Abelonii; also Abelites, [1] Abeloites or Abelonians) were a Christian sect that emerged in the 4th century in the countryside near Hippo Regius in north Africa during the reign of Arcadius. [2] [1] They lived in continence as they affirmed Abel did. They were required to be married but were forbidden to consummate the marriage.
In the case of finitely generated abelian groups, this theorem guarantees that an abelian group splits as a direct sum of a torsion group and a free abelian group. The former may be written as a direct sum of finitely many groups of the form Z / p k Z {\displaystyle \mathbb {Z} /p^{k}\mathbb {Z} } for p {\displaystyle p} prime, and the latter ...
This common order must be a prime number, and the elementary abelian groups in which the common order is p are a particular kind of p-group. [1] [2] A group for which p = 2 (that is, an elementary abelian 2-group) is sometimes called a Boolean group. [3] Every elementary abelian p-group is a vector space over the prime field with p elements ...
Abelian groups of rank 0 are exactly the periodic abelian groups. The group Q of rational numbers has rank 1. Torsion-free abelian groups of rank 1 are realized as subgroups of Q and there is a satisfactory classification of them up to isomorphism. By contrast, there is no satisfactory classification of torsion-free abelian groups of rank 2. [2]
Dedekind and Baer have shown (in the finite and respectively infinite order case) that every Hamiltonian group is a direct product of the form G = Q 8 × B × D, where B is an elementary abelian 2-group, and D is a torsion abelian group with all elements of odd order. Dedekind groups are named after Richard Dedekind, who investigated them in ...
An abelian group A is torsion-free if and only if it is flat as a Z-module, which means that whenever C is a subgroup of some abelian group B, then the natural map from the tensor product C ⊗ A to B ⊗ A is injective. Tensoring an abelian group A with Q (or any divisible group) kills torsion. That is, if T is a torsion group then T ⊗ Q = 0.
The symmetric group on three points is an A-group that is not abelian. Every group of cube-free order is an A-group. The derived length of an A-group can be arbitrarily large, but no larger than the number of distinct prime divisors of the order, stated in , and presented in textbook form as (Huppert 1967, Kap. VI, Satz 14.16). The lower ...
