On q-Wiener index of some graph operations

Youchuang Lin, Jianping Ou, Yingying Qin

Abstract


The q-Wiener index of graphs is a generalization of the classical Wiener index. This paper determines the q-Wiener index of graphs constructed by graph operations such as Join, Symmetric difference, Composition, Disjunction. Some known results are direct consequence of these observations.

Keywords
