| Abstract. | In this paper, we raise a new concept λ-modified Hyper-Wiener index to measure the topological structure of molecular graphs. We consider the relationship between λ-modified Hyper-Wiener index and some special parameters of molecular graph, and present the molecular graphs which minimize the λ-modified Hyper-Wiener index with λ>0 among all molecular graphs with given chromatic number and clique number and the molecular graphs which maximum the λ-modified Hyper-Wiener index among all molecular graphs with given clique number. |
