Sharp Lower Bounds of the Sum-Connectivity Index of Unicyclic Graphs
The sum-connectivity index of a graph G is defined as the sum of weights 1/du+dv over all edges uv of G, where du and dv are the degrees of the vertices u and v in graph G, respectively. In this paper, we give a sharp lower bound on the sum-connectivity index unicyclic graphs of order n≥7 and diamet...
