In abstract algebra, a free abelian group or free Z-module is an abelian group with a basis. scriptstyle a(mn) ,= , a(m)a . The following 31 pages are in this category, out of 31 total. Examples of Abelian groups- (Z,+), (V,+). 13 More on free abelian groups. The number of Abelian groups of order n is multiplicative, i.e. 1.1 Definition 1; 1.2 Definition 2. For n = 0 and n = 1 (the empty set and the singleton set) the symmetric group is trivial (note that this agrees with 0! (Every finite dimensional real vector space is an abelian group that is iso- morphic to certain Rn.) Ex 2.46. A finite abelian group can be expressed as a direct product of its Sylow p- subgroups. It is abelian if and only if n ≤ 2. Which is part of the R -module structure of the set of matrices M_(n,m)(R) . The abelian-groups tag has no usage guidance.
