They are similar to edge-PI and vertex-Szeged indices, respectively. The different versions of Szeged and PIindices are the most important topological indices defined in Chemistry. In this paper, we compute the edge-Szeged and vertex-PIindices of some important classes of benzenoid systems. %> http://ijmsi.ir/article-1-42-en.pdf %P 31-39 %& 31 %! %9 Research paper %L A-10-1-40 %+ %G eng %@ 1735-4463 %[ 2008
