λ-Modified Extremal Hyper-Wiener Index of Molecular Graphs

Journal of Applied Computer Science & Mathematics, 2014
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 ...

Sufficient Conditions for Wiener Index, Hyper-Wiener Index and Harary Index of the Hamilton Graph

Mathematics and Computer Science
The topological index can be used to depict the structural properties of graphs, and the Hamiltonian problem of graphs has always been a classical problem in graph theory. In this work, we use some known conditions to give some sufficient conditions for Hamilton graphs by the Wiener index, Hyper-Wiener index and Harary index of a graph.
