Let be an abelian group. A graph is called -magic if there exists edge labeling such that the induced vertex set labeling , defined by , where the sum is over all edges in , is a constant map. A graph is -barycentric-magic (or has -barycentric labeling) if is -magic and also satisfies for all and for some vertex adjacent to . In this paper we consider some graphs and characterize all for which is -barycentric-magic.
