• EDGE VERSION OF INVERSE SUM INDEG INDEX OF CERTAIN NANOTUBES AND NANOTORI

V. R. KULLI*

Abstract


Chemical graph theory is a branch of graph theory whose focus of interest is to finding topological indices of chemical molecular graphs, which correlate well with chemical properties of the chemical molecules. A topological index is a numerical parameter mathematically derived from the graph structure. In this paper, we compute the edge version of inverse sum indeg index of certain nanotubes and nanotori.


Keywords


molecular graph, inverse sum indeg index, nanotubes, nanotori.
