Amazon.com description: Product Description: This book gives an introduction to Jacques Tit's theory of buildings, a subject in which there is a rich interplay between group theory and geometry. The book starts from scratch, with a discussion of finite reflection groups, and takes the reader to the literature on buildings. The prerequisites are kept to a minimum, and careful attention is paid to motivating new concepts that are introduced. The book should be accessible to any mathematics graduate student who knows very little group theory and topology.
