摘要：

Let G be a group, and let (Gamma(C)) over bar (G) be a digraph whose vertices are the non-trivial conjugacy classes of G and there is an arc from a vertex C to a vertex C' if and only if C not equal C' and < C > subset of < C'>. In this paper, we characterize finite groups G whose associated digraphs (Gamma(C)) over bar (G) are oriented trees.
