Abstract

The Padmakar-Ivan (PI) index is a Wiener-Szeged-like TOPOLOGICAL INDEX which reflects certain structural features of organic molecules. The PI INDEX of a graph G is the sum of all edges uv of G of the number of edges which are not equidistant from the vertices u and v. In this paper we obtain the second and third extremals of CATACONDENSED HEXAGONAL SYSTEMs with respect to the PI INDEX.
