11 PREFACE TO THE SIXTH EDITION Since publication of the fifth (1984) edition of this book there has been a tremendous amount of activity in discrete subgroups of Lie groups and algebraic groups. This activity had emphasis in several areas, especially differential geometry, harmonic analysis, algebraic geometry and number theory. It also had applications via Fourier transform theory to signal processing and other areas. Most of the new material in this sixth (2010) edition represents an attempt to indicate some of these developments. Much of this is done in Chapter 3 and in the Appendix to Chapter 12. Chapter 3 has some new results and an indication of updates in the section on flat homogeneous pseudo riemannian manifolds. The Appendix to Chapter 12 sketches some background and a brief description (sometimes just consisting of current references) of the more recent work on discrete subgroups of real Lie groups. There the emphasis is on application to pseudo riemannian geometry and pseudo riemannian quotient manifolds, including of course the riemannian case. There has also been an enormous amount of work on spaces of functions on those quotients, but that is well beyond the scope of this book. I thank Oliver Baues for his generous advice and updates concerning the revision of Chapter 3. Thanks also to Jonathan Wahl in connection with the change in the Remark on page 170. I was tempted to modernize the finite group theory in Chapter 6, but that could have made it inaccessible to many differential geometers, and I thank James Milgram and C. T. C. (Terry) Wall for convincing me not to do it. Finally, my thanks to Hillel Furstenberg, David Kazhdan and Toshiyuki Kobayashi for updates and references in the Appendix to Chapter 12. In this new material, note that citations not in the 1986 References section are in Additional References just after. As ever, special thanks are due to my wife Lois for her support while I was preparing this new edition. Berkeley, July 2010 J. A. W. x
