Multiplicative-sum Zagreb index of splice, bridge, and bridge-cycle graphs
The multiplicative-sum Zagreb index is a graph invariant defined as the product of the sums of the degrees of pairs of adjacent vertices in a graph. In this paper, we compute the multiplicative-sum Zagreb index of some composite graphs such as splice graphs, bridge graphs, and bridge-cycle graphs i...
