Reduced Sombor coindex of Graph Operations

Abstract

Here, we introduce a new parameter, called reduced Sombor coindex and we compute the results
on reduced Sombor coindex for certain standard graphs. Also, we concerned to compute the reduced Sombor
coindex of certain graph operations like cartesian product, strong product, direct product, lexicographic
product of two graphs. We also compute the bounds of the reduced Sombor coindex. The chemical applicability
of this parameter is discussed by comparing it with the π-electron energy of some selected hetero molecules
and by comparing it with the π-electron energy of some selected PAHs.
