• MULTIPLICATIVE SOMBOR INDICES OF CERTAIN NANOTUBES

V. R. KULLI*

Abstract


A topological index is a numeric quantity from structural graph of a molecule. In this paper, we introduce the multiplicative Sombor index, multiplicative modified Sombor index, multiplicative reduced Sombor index and multiplicative reduced modified Sombor index of a graph. Furthermore we compute these multiplicative Sombor indices for certain nanotubes.


Keywords


multiplicative Sombor index, multiplicative modified Sombor index, multiplicative reduced Sombor index, nanotube.
