摘要
图的Randic能量定义为图的Randic矩阵所有特征值的绝对值之和,本文通过原图的Randic矩阵和剖分图的Randic矩阵之间的关系刻画了完全图、完全二部图、友谊图和荷兰风车图的剖分图的Randic能量。
The Randic energy of the graph is the sum of the absolute values of all the eigenvalues of the graph's Randic matrix.In this paper,for the complete graph,complete bipartite graph,friendship graph and dutch windmill graph,we characterize the Randic energy of their subdivision graph by the relationship between the Randic matrix of themselves and the Randic matrix of their subdivision graph.
