• ON SECOND BANHATTI-SOMBOR INDICES

V. R. KULLI*

Abstract


Recently, a novel class of degree based topological indices was introduced, the so called Banhatti-Sombor indices. In this paper, we introduce the second Banhatti-Sombor index, second reduced Banhatti-Sombor index, second d-Banhatti-Sombor index of a graph and compute exact formulas for some chemical networks such as armchair polyhex nanotubes, zigzag polyhex nanotubes and carbon nanocone networks.


Keywords


second Banhatti-Sombor index, second reduced Banhatti-Sombor index, second- Banhatti-Sombor index, nanotube, network.
