Some Structural Properties of AG-Groups

An AG-group ( an AG-groupoid with left identity and inverses) is a nonassociative structure in general midway between a quasigroup and an abelian group. This paper is meant to re-start the study of AG-groups. We prove that for an AG-group associativity and commutativity imply each other. Nonassociative AG-groups can never be power associative. The duality between left AG-groups and right AG-groups is also discussed.
