Computing the Narumi-Katayama index and modified Narumi-Katayama index of some families of dendrimers and tetrathiafulvalene (Q2230064)

Summary: A dendrimer is an artificially manufactured or synthesized molecule built up from branched units called monomers. In mathematical chemistry, a particular attention is given to degree-based graph invariant. The Narumi-Katayama index and its modified Narumi-Katayama index of a graph \(G\) denoted by \(\mathrm{NK}(G)\) and \(\mathrm{NK}^\ast(G)\) are equal to the product of the degrees of the vertices of \(G\). In this paper, we calculate the Narumi-Katayama Index and modified Narumi-Katayama index for some families of dendrimers.
