• DIRECT AND INVERSE SUM BANHATTI INDICES

V. R. KULLI*

Abstract


We introduce the direct and inverse sum Banhatti indices of a molecular graph, In this paper, we compute the direct and inverse sum Banhatti indices of some standard clases of graphs. Also the direct and inverse sum Banhatti indices of certain nanotubes are determined.


Keywords


molecular graph, direct and inverse sum Banhatti indices, nanotube.
