摘要
The maximum matching graph a"(3)(G) of a graph G is a simple graph whose vertices are the maximum matchings of G and where two maximum matchings are adjacent in a"(3)(G) if they differ by exactly one edge. In this paper, we prove that if a graph is isomorphic to its maximum matching graph, then every block of the graph is an odd cycle.
