• ON SZEGED INDEX OF STANDARD GRAPHS

K. V. S. Sarma*, I. V. N. Uma**

Abstract


A recently introduced graph-invariant is ‘Szeged Index’ and it has considerable applications in molecular chemistry. In this paper, the Szeged indices of standard graphs are calculated. A modified Szeged index of a graph is also introduced in which all the vertices of the graph are taken into consideration; thereby the variations in these indices of standard graphs are identified.


Keywords


Wiener number, Szeged index, modified Szeged index.
