The inquiry into identifying sets of monomials that can be eliminated from a generic homogeneous polynomial via a linear change of coordinates was initiated by E. K. Wakeford in [10]. This linear algebra problem prompted C. K. Fan and J. Losonczy to introduce the notion of acyclic matchings in the additive group $\mathbb{Z}^n$ in [5], subsequently extended to abelian groups by the latter author[9]. Alon et al., in [4], established the acyclic matching property for $\mathbb{Z}^n$. This note aims to classify all abelian groups with respect to the acyclic matching property.
Comment: Fixed some minor errors. Added Remark 2.7. Comments are welcome
