On Wiener Index for Generalised Subdivision Neighbourhood Corona of Graphs
International Journal of Mathematics and Mathematical SciencesGraph operations such as the corona product play a significant role in analysing and constructing complex networks. In this work, we examine the Wiener index within the framework of generalised subdivision graph operations.

Croatica Chemica Acta, 2004 If two edges e and f are deleted from a tree T, then it decomposes into three components, possessing, n0(e, f ), n1(e, f ), and n2(e, f ) vertices. Let n0(e, f ) count the vertices lying between the edges e and f. It is shown that the Wiener index W of the tree T is equal to the sum over all edges e of the products n1(e, e) • n2(e, e), and that the ...

The structure of graphs with extremal hyper-Wiener index
FilomatThe hyper-Wiener index of a graph G is defined as WW(G) = 1/2 ?{u,v}?V(G) (d2G(u,v)+dG(u,v)), where dG(u,v) denotes the distance between u and v in G. In this paper, we determine the maximum hyper-Wiener index of 2-connected graphs and 2-edge-connected graphs, which extends the result of Plesnik [On the sum of all distances in a graph or digraph, J ...

λ-Modified Extremal Hyper-Wiener Index of Molecular Graphs
Journal of Applied Computer Science & Mathematics, 2014 In this paper, we raise a new concept λ-modified Hyper-Wiener index to measure the topological structure of molecular graphs. We consider the relationship between λ-modified Hyper-Wiener index and some special parameters of molecular graph, and present the molecular graphs which minimize the λ-modified Hyper-Wiener index with λ>0 among all molecular ...
