HYPER-WIENER INDEX ON LEVEL-3 SIERPINSKI GASKET

Fractals
The hyper-Wiener index plays an important role in chemical graph theory. In this paper, using the technique named finite pattern, we discuss the hyper-Wiener index on level-3 Sierpinski gasket which is a self-similar fractal.

Hyper-Wiener index for acyclic structures

Journal of Structural Chemistry, 1999
The discriminating ability of the hyper-Wiener index (the ability to discriminate between isomers) is discussed on a class of acyclic structures (trees) including the molecular graphs of alkanes. For trees with 4 to 26 vertices, numerical data on the classes of trees with coincident indices were obtained. For classes with maximal power, the diagrams of

Bond order weighted hyper-Wiener index

Journal of Molecular Structure: THEOCHEM, 2003
Abstract In this work the hyper-Wiener index calculated and are weighted by Mulliken bond orders. We have considered several formaldehyde derivatives to try to relate these values to an actual physical property (vibrational frequencies in this case). This was done in order to establish a relation between the quantities.

Bounds on hyper-Wiener index of graphs

Asian-European Journal of Mathematics, 2017
The Wiener number [Formula: see text] of a graph [Formula: see text] was introduced by Harold Wiener in connection with the modeling of various physic-chemical, biological and pharmacological properties of organic molecules in chemistry. Milan Randić introduced a modification of the Wiener index for trees (acyclic graphs), and it is known as the hyper-

The extended hyper-Wiener index

Canadian Journal of Chemistry, 2003
According to the definition of molecular connectivity and the definition of a hyper-Wiener index, a novel set of hyper-Wiener indexes (Rn, mRn) are defined and are named the extended hyper-Wiener indexes. Where n = 1, 2, 3, 4,... represents the type of subgraph units and is the number of endmost atoms of the subgraph unit, m is the number of atoms of ...
