摘要:
Let G be a simple connected graph with the vertex set V(G). The Gutman index Gut(G) of G is defined as Sigma ({x, y} subset of V(G)) d(G)(x) d(G)(y) d(G)(x, y), where d(G)(v) is the degree of the vertex v in G and do (x, y) the distance between the vertices x and y in G. In this paper, the second-minimum Gutman index of the unicyclic graphs on n vertices and girth m is characterized.
