Overview

"Spherical buildings are certain combinatorial simplicial complexes intro­ duced, at first in the language of ""incidence geometries,"" to provide a sys­ tematic geometric interpretation of the exceptional complex Lie groups. (The definition of a building in terms of chamber systems and definitions of the various related notions used in this introduction such as ""thick,"" ""residue,"" ""rank,"" ""spherical,"" etc. are given in Chapter 39. ) Via the notion of a BN-pair, the theory turned out to apply to simple algebraic groups over an arbitrary field. More precisely, to any absolutely simple algebraic group of positive rela­ tive rank £ is associated a thick irreducible spherical building of the same rank (these are the algebraic spherical buildings) and the main result of Buildings of Spherical Type and Finite BN-Pairs [101] is that the converse, for £ ::::: 3, is almost true: (1. 1) Theorem. Every thick irreducible spherical building of rank at least three is classical, algebraic' or mixed. Classical buildings are those defined in terms of the geometry of a classical group (e. g. unitary, orthogonal, etc. of finite Witt index or linear of finite dimension) over an arbitrary field or skew-field. (These are not algebraic if, for instance, the skew-field is of infinite dimension over its center. ) Mixed buildings are more exotic; they are related to groups which are in some sense algebraic groups defined over a pair of fields k and K of characteristic p, where KP eke K and p is two or (in one case) three."

From the reviews: In this excellently written book, the authors give a full classification for Moufang polygons. ... The book is self contained ... . the content of the book is accessible for motivated graduate students and researchers from every branch of mathematics. We recommend this book for everybody who is interested in the developments of the modern algebra, geometry or combinatorics. (Gabor P. Nagy, Acta Scientiarum Mathematicarum, Vol. 71, 2005) The publication of this long-awaited book is a major event for geometry in general, and for the theory of buildings in particular. ... The classifications established in this book are splendid achievements of fundamental significance. The whole book is extremely well written, in a clear and concise style ... . It is the definitive treatment and a standard reference. (Theo Grundhoefer, Mathematical Reviews, Issue 2003 m) This book contains the complete classification of all Moufang generalized polygons, including the full proof. ... So, in conclusion, the book is a Bible for everyone interested in classification results related to spherical buildings. It is written in a very clear and concise way. It should be in the library of every mathematician as one of the major results in the theory of (Tits) buildings, (combinatorial) incidence geometry and (algebraic) group theory.
