Mean-Value Formulae for the Neighbourhood of the Typical Cell of a Random Tessellation

Abstract

The mean number of edges of a randomly chosen neighbouring cell of the typical cell in a planar stationary tessellation, under the condition that it hasnedges, has been studied by physicists for more than 20 years. Experiments and simulation studies led empirically to the so-calledAboav's law.This law now plays a central role in Rivier's (1993) maximum entropy theory of statistical crystallography. Using Mecke's (1980) Palm method, an exact form of Aboav's law is derived. Results in higher-dimensional cases are also discussed.
