Introduction: Reflection groups and invariant theoryding its orthogonal vectors to their negatives. A . is, then, any group of transformations generated by such reflections. The purpose of this book is to study such groups and their associated invariant theory, outlining the deep and elegant theory that they possess.

Bilinear forms of Coxeter systemstion between finite reflection groups and Coxeter systems developed in §6–2. The main result of this chapter is that the bilinear form associated to a Coxeter system is always positive definite. In Chapter 8, we shall use the positive definiteness of this bilinear form to classify both finite Coxeter systems and finite Euclidean reflection groups.

Pseudo-reflectionswell as the next, is preliminary to the study of invariant theory, since it is invariant theory that motivates the introduction of pseudo-reflections. Most of our discussion of invariant theory naturally takes place in the context of pseudo-reflection groups. However, it will take several chapters before we are able to demonstrate this point.
