Authors’ abstract: The power graph of a group \(G\) is a directed graph with the set \(G\) of vertices, and with all edges \((u,v)\) such that \(u\neq v\) and \(v\) is a power of \(u\). For each directed graph \(D\), we give a complete description of all groups \(G\) such that every infinite subset of \(G\) contains a power subgraph isomorphic to \(D\). Also, we describe the structure of the power graphs of all finite abelian groups.
