摘要 图的匹配能量定义为该图的匹配多项式的零点的绝对值之和.设U(n,d)为n阶且直径为d的连通单圈图的集合,刻画了U(n,d)中取到极小匹配能量的极图. The matching energy of a graph was defined as the sum of the absolute values of zeros of its matching polynomial. Let U( n,d) be the set of connected unicyclic graphs of order n and diameter d,the graph from U( n,d)minimizing the matching energy is completely characterized.
