Paper Title:
Edge-PI Index of TUC4C8(S) Nanotubes
  Abstract

Carbon nanotubes show remarkable mechanical properties. Experimental studies have shown that they belong to the stiffest and elastic known materials. These good properties are connect with their topological indices of molecules. Recently computing topological indices of nanostructures have been the object of many papers. The edge version of Padnakar-Ivan (PI) index is a graph invariant defined as PI =\sum_{e\in E(G)}[nu(e)+nv(e)], where e=uv, nu(e) is the number of edges of G lying closer to u than to v and nv(e) is the number of edges of G lying closer v than to u. In this paper, an exact expression for edge-PI index of TUC4C8(S) nanotubes is given.
