Hosoya Indices of Bicyclic Graphs [PDF]

, 2009
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 Bn denote the set of bicyclic graphs on n vertices.

The smallest Hosoya index of unicyclic graphs with given diameter [PDF]

, 2012
The Hosoya index of a (molecular) graph is defined as the total number of the matchings, including the empty edge set, of this graph. Let ${\cal{U}}_{n,d}$ be the set of connected unicyclic (molecular) graphs of order n with diameter d. In this paper we
