From the Inside Flap
The authors clearly had user-friendliness in mind in preparing this edition. Revisions have focused on clarification of presentation, the numbering of results from the original edition has been retained, and the new final chapter is organized so that Section 12.k gives updates relevant to Chapter k. The original bibliography has been expanded to about double its original length. This new edition will serve to continue to make this book a useful introduction to and reference in its field.
