Appendix

Abstract

Up until the last chapter, we have adopted throughout this book a purely algebraic and graph-theoretical point of view with prerequisites of the most elementary kind. In this appendix, we take a closer look at some of the results concerning algebraic buildings (especially those concerning existence and automorphisms) allowing now the use, without definitions or proofs except possibly for heuristic substitutes, of standard notions and results of algebraic group theory and Galois descent. Further details about those can be found, for instance, in [7], [8], II, §1, of [18], [26] and [95].
