Higher Values of the Applied Field,x sets which shall be used later in the special case of convex polytopes; certain other properties are investigated which do not hold for all convex sets but are valid (and important) for more restricted families such as compact convex sets, polyhedral sets, or polytopes. We discuss these properties

Higher Values of the Applied Field,difficulty of producing polytopes having certain desired features. One example of such a difficulty will help to focus the problem. Let us consider 4-polytopes with 8 vertices; with some patience, combining the different types of polytopes considered in Chapter 4, the reader will probably find 4-pol

Statistical Mechanics for a Vortex Gas,l of all the .-vectors of polytopes in the class considered. In other words, we were concerned with the linear relations satisfied by the .-vectors of all polytopes belonging to a certain class. Chapter 10 reports on the present knowledge about non-linear relations existing between the components of

One of the main problems is to find criteria for deciding whether a given polytope is ., that is to say, can be expressed as a’ sum’ (in either sense)

Statistical Mechanics for a Vortex Gas,polytopes or else, though meaningful for a larger class of sets, reduce in their most interesting aspects to polytopes. Clearly, the number of such topics could be increased almost without bounds, and the selection of those dealt with here reflects only the author’s predilections and interests.

A deeper reason is that, from many combinatorial points of view, 3-polytopes may be replaced by planar graphs. The various techniques of graph theory are therefore applicable to the study of 3-polytopes.
