Szeged index of a class of unicyclic graphs
Xuli Qi;Abstract
The Szeged index is a modification of the Wiener index to cyclic molecules. We determine the n-vertex unicyclic graphs whose vertices on the unique cycle have degree at least three with the first, the second and the third smallest as well as largest Szeged indices for n>=6, n>=7 and n>=8,respectively.
