Ordered abelian group

In mathematics, an abelian group, also called a commutative group, is a group in which the result of applying the group operation to two group elements does not depend on the order in which they are written. That is, the group operation is commutative.

For this, the group law o has to contain the following relation: x∘y=x∘y for any x, y in the group. As compare to the non-abelian group, the abelian group is simpler to analyze. When the group is abelian, many interested groups can be simplified to special cases.

We consider an ordered abelian group G= [x] in which the identity 6 is not isolated: if x, y>6 in G then x+y>d; there is an x^d; and if x>6 there is a y such that 6 WebIn 1907, Hahn [2] showed that every (totally) ordered abelian group can be embedded in a lexicographically ordered, real function space. His proof occupies twenty-seven pages, not counting preliminaries, and may well be described as a transfinite marathon. For forty-five years, no one offered a simpler proof.

Conversely, F. W. Levi showed that a torsion-free abelian group is bi-orderable; this is still true for nilpotent groups but there exist torsion-free, finitely presented groups which are not left-orderable. Otto Hölder showed that every Archimedean group (a bi-ordered group satisfying an Archimedean …
