ON MULTIPLICATIVE SUM ZAGREB INDEX OF TREES WITH FIXED DOMINATION NUMBER

The multiplicative sum Zagreb index of a graph G is the product of the sums of de-grees of pairs of adjacent vertices. In this paper, the maximal and minimal multiplicative sum Zagreb indices of trees with fixed domination number are presented. Furthermore, the corre-sponding extremal trees are identified.
