A Generaligation for the Evaluation Formula of Graph Hosoya's Indices
Ma Jinliang Department of Management Engineering
To research on Hosoya's indices has profound significance. The index showed physical and chemical nature of compound structure in molecular topology is very important. The topology structure of compound with cycles can be regarded as a category of graph with rings. At present, the algorithm of nonconjuncted number of the graph with a ring is unsolved. This paper presents a evaluating formula of Hosoya's indices, and makes certain of some new conclusions.
