Abstract

For molecular graph $G$, the first multiplicative Zagreb index is defined as the product of squares of degree of all vertices of graph and the second multiplicative Zagreb index is defined as $\prod_2(G) =\prod\limits_{u\in V(G)} d_G(u)^{d_G(u)}$. In this paper, we obtain first and second multiplicative Zagreb indices of four new $\mathcal{F}$-Sums of graphs.
