Additive groups of rings The additive group of a ring is an abelian group, but not all abelian groups are additive groups of rings (with nontrivial multiplication).
Although the definition assumes that the additive group is abelian, this can be inferred from the other ring axioms.
Additivity If C and D are preadditive categories and F : C ← D is an additive functor with a right adjoint G : C → D, then G is also an additive functor and the hom-set bijections : are, in fact, isomorphisms of abelian groups.
Analogously, one can show that the cokernel functors for abelian groups, vector spaces and modules are left adjoints.
Any group of prime order is isomorphic to a cyclic group and therefore abelian.
Any one-dimensional Lie algebra over a field is abelian, by the antisymmetry of the Lie bracket.
