摘要

图 H 的类图形 G 是以 H 的类图形盖 Ψ 为顶点得到的图形，当且仅当对应路径有非空交集时，两个顶点相邻。如果 G 与其中一个图形同构，则称 G 为自图形。如果 G 与其中一个互补图形同构，则称 G 为自互补图形。在本文中，我们将描述自形图的特征，并给出从循环图和车轮图构建自形图的方法。此外，我们还给出了自互补图形的特征。

On self-graphoidal graphs and their complements

The graphoidal graph $G$ of graph $H$ is the graph obtained by taking graphoidal cover $Ψ$ of $H$ as vertices and two vertices are adjacent if and only if the corresponding paths have a non-empty intersection. If $G$ is isomorphic to one of its graphoidal graphs, then $G$ is said to be a self-graphoidal graph. $G$ is called self-complementary graphoidal graph if it is isomorphic to one of its complementary graphoidal graphs. In this article, we characterize self-graphoidal graphs and give a construction of self-graphoidal graphs from cycle and wheel graphs. Also, we give a characterization of self-complementary graphoidal graphs.
