Chromatic Numbers and the Kneser Conjectureathematics and algebraic topology, whose solutions benefit from the interaction of the two fields. Usually, this implies constructing a topological space starting with a discrete object as an input, or, conversely, providing a discrete model for an already existing geometric or topological setting.

Structural Theory of Morphism Complexesbout this family of prodsimplicial complexes is that Hom _(-, -) complexes are fully determined by the low-dimensional data; in fact, it turns out that already knowing the 1-skeleton suffices; cf. Definition 9.16.

Yet the aspects of the theory that we consider here and that we distinguish under the title of this book are far from classical and have been brought to the attention of the general mathematical public fairly recently.

Methodology, research design, and methods,tried to assemble a number of relevant results to entice the reader to consult the standard texts. Most of the given proofs are sketchy, though the proofs of the statements that are needed for later applications are complete.

Situation Awareness with Systems of Systemsis purely combinatorial. In this chapter we survey many different situations in which complexes defined by combinatorial data arise. While a certain attempt to structure this set of examples is taken, a complete classification is impossible, due to the nature of the subject.

One structural approach is to view . as an acyclic category and to view the group action of . as a functor from the one-element category associated to the group . to .. Then, as we have pointed out earlier in Subsection 4.4.3, it is natural to define . to be
