Kirchhoff Index

The Kirchhoff index , also simply called the resistance and denoted  (Lukovits et al. 1999), of a connected graph  on  nodes is defined by

where  is the resistance distance matrix.

Unless otherwise stated, hydrogen atoms are usually ignored in the computation of such indices as organic chemists usually do when they write a benzene ring as a hexagon (Devillers and Balaban 1999, p. 25).

Precomputed values for many graphs are implemented in the Wolfram Language as GraphData[g, "KirchhoffIndex"].

The following table summarizes values of the Kirchhoff index for various special classes of graphs.
