In order to avoid technicalities in this introductory chapter, we confine our attention to . groups and we require our reflections to be with respect to . hyperplanes (i.e., hyperplanes passing through the origin). We will generalize this in Chapter VI, replacing “finite” by “discrete” and “linear” by “affine”.

Mathematik für Naturwissenschaftler II. Following Tits, we will call ∑ the . associated to (.,.). The word “complex” will be justified below, when we prove that ∑ is indeed a simplicial complex. The purpose of this chapter is to develop the geometric properties of Coxeter complexes.

Differential- und Integralrechnung, to motivate this definition. In particular, you will probably wonder how someone (namely, Tits) came up with these axioms. I will not attempt to answer this question now, but I will make some historical remarks in the next chapter (§V.4) which should make the definition seem less mysterious.

Mathematik für Naturwissenschaftlerchapter is a familiarity with the basic facts about group cohomology, as given for instance in . I will also use some algebraic topology (fundamental group, covering spaces, homology theory of manifolds, etc.).
