摘要：

Given a molecular graph G, the Hosoya index Z(G) of G is defined as the total number of the matchings of the graph. Let B-n denote the set of bicyclic graphs on n vertices. In this paper, the minimal, the second-, the third-, the fourth-, and the fifth-minimal Hosoya indices of bicyclic graphs in the set B-n are characterized.
