WebIn this paper, we introduce the atom bond connectivity Revan index and geometric-arithmetic Revan indices of a molecular graph. Furthermore, we determine the sum connectivity Revan index, atom bond connectivity Revan index and geometric-arithmetic Revan index of chemically interesting drugs like jagged-rectangle benzenoid systems … WebOn the Minimal General Sum-Connectivity Index of Connected Graphs Without Pendant Vertices Abstract: The general sum-connectivity index of a graph $G$ , denoted by …

The Gourava Indices and Coindices of Graphs - [scite report]

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.
