WebWhen Gis an abelian group, the order of the factors here is unimportant, and then we can simply say that f(x) is an identity of ϕ. Definition 1.2. We say that a polynomial f(x) ∈ Z[x] is an elementary abelian identity of ϕif f(x) is an identity of the automorphisms induced by ϕon every characteristic elementary abelian section of G. Any left- or right-orderable group is torsion-free, that is it contains no elements of finite order besides the identity. 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 … crypto robot review au https://h2oattorney.com
