On the entire Zagreb indices of the line graph and line cut-vertex graph of the subdivision graph
Let \(G=(V,E)\) be a graph. Then the first and second entire Zagreb indices of \(G\) are defined, respectively, as \(M^{ε}_{1}(G)=∑_{x∈V(G)∪E(G)}(d_{G}(x))^{2}\) and \(M^{ε}_{2}(G)=∑_{{x,y}∈B(G)}d_{G}(x)d_{G}(y)\), where \(B(G)\) denotes the set of all 2-element subsets \({x,y}\) such that \({x...
