Web4 4. Cyclic Groups. Deﬁnition If there exists a group element g ∈ G such that hgi = G, we call the group G a cyclic group. We call the element that generates the whole group a generator of G. (A cyclic group may have more than one generator, and in certain cases, groups of inﬁnite orders can be cyclic.) Examples will make this very clear. WebFor an abelian group G, the set G ˝:= fu2Gjjujis niteg forms a subgroup, called the torsion subgroup of G. If G= G ˝, then Gis said to be a torsion group. If G ˝ = 0, then Gis said to be torsion-free. Here is the structure theorem of nitely generated abelian groups. Thm 2.11. Let Gbe a nitely generated abelian group. Then G= G ˝ F; where F’Zs
