WebThe sum-connectivity index of a graph G is defined as the sum of weights 1 / d u + d v over all edges u v of G , where d u and d v 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 diameter D G ≥ 5 . Download Full-text Web30 de mai. de 2015 · The sum-connectivity index of the graph G is defined as \chi (G) = \sum\nolimits_ {v_i v_j \in E (G)} { (d_i + d_j )^ { - 1/2} } . We discuss the effect on χ ( G) of inserting an edge into a graph. Moreover, we obtain the relations between sum-connectivity index and Randić index. Download to read the full article text References
