Sharp Bounds of First Zagreb Coindex for F-Sum Graphs
Let G=VE,EG be a connected graph with vertex set VG and edge set EG. For a graph G, the graphs S(G), R(G), Q(G), and T(G) are obtained by applying the four subdivisions related operations S, R, Q, and T, respectively. Further, for two connected graphs G1 and G2, G1+FG2 are F-sum graphs which are con...
