Abelian group

  • Page ID
  • An abelian group, also called a commutative group, is a group (G, * ) such that g1 * g2 = g2 * g1 for all g1 and g2in G, where * is a binary operation in G. This means that the order in which the binary operation is performed does not matter, and any two elements of the group commute.

    Groups that are not commutative are called non-abelian (rather than non-commutative).

    Abelian groups are named after Niels Henrik Abel.
