The number of ways to label a structure
(Springer-Verlag; Psychometric Society, 1967-06)
It has been observed that the number of different ways in which a graph with p points can be labelled is p ! divided by the number of symmetries, and that this holds regardless of the species of structure at hand. In this ...
A graph theory interpretation of nodal regions
(Springer-Verlag; The Regional Science Association, 1961-12)
The techniques defined in this paper will divide a set of cities into subgroups which specify a central place and its subordinate hierarchy. The association between cities is not the only system which may be defined as a ...
An approach to the direct measurement of community mean information fields
(Springer-Verlag; The Regional Science Association, 1963-12)
Computation of the correspondence of geographical patterns
(Springer-Verlag; The Regional Science Association, 1965-12)
The probability of a given 1-choice structure
(Springer-Verlag; Psychometric Society, 1966-06)
A 1-choice structure arises whenever each person in a group chooses exactly one other person according to some criterion. Our purpose is to study the situation in which these choices are made at random. As noted in Harary, ...
A graph theoretic approach to similarity relations
(Springer-Verlag; Psychometric Society, 1964-06)
A similarity relation is reflexive and symmetric. A graph may be regarded as a geometric representation of an irreflexive symmetric relation; an r -graph then coincides with a similarity relation. For the realization of ...
Asia on the Eve of Europe's Expansion
(Prentice-Hall, 1965)
Map in the frontispiece of the included book based on an original map by Sandra Lach (now, Arlinghaus--sarhaus@umich.edu). The book is peer-reviewed. There is also a file listing a box by box inventory of the works of ...
