Viral products and ideas are intuitively understood to grow through a person-to-person
diffusion process analogous to the spread of an infectious disease; however, until recently it …

This book deals with the analysis of the structure of complex networks by combining results
from graph theory, physics, and pattern recognition. The book is divided into two parts. 11 …

Every branch of mathematics employs some notion of a product that enables the com-
bination or decomposition of its elemental structures. In graph theory there are four main …

New Edition! Completely Revised and UpdatedChemical Graph Theory, 2nd Edition is a
completely revised and updated edition of a highly regarded book that has been widely …

Let G be a graph on n vertices. Its Laplacian matrix is the n-by-n matrix L (G) D (G)− A (G),
where A (G) is the familiar (0, 1) adjacency matrix, and D (G) is the diagonal matrix of vertex …

The Wiener index W is the sum of distances between all pairs of vertices of a (connected)
graph. The paper outlines the results known for W of trees: methods for computation of W …

There are several different broad approaches to making correlations between chemical
structure and some desired property or bioactivity (either of which is here spoken of simply …

Tree balance plays an important role in phylogenetics and other research areas, which is
why several indices to measure tree balance have been introduced over the years …

The Wiener index W is the sum of distances between all pairs of vertices of a (connected)
graph. Hexagonal systems (HS's) are a special type of plane graphs in which all faces are …

Sažetak The definitions and methods of computing the Wiener index are reviewed. It is
pointed out that the Wiener index is a useful topological index in the structure-property …
