This final chapter is a survey, without proofs, of a few of the applications of buildings to the cohomology theory of groups, A prerequisite for this chapter 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.).
