A review of the second edition appeared in Issue 44 of this Newsletter (June 2002). The third edition follows the arrangement of topics of the second edition. However, a considerable number of proofs have been simplified or clarified, and many exercises have been revised and rearranged. In the preface, the authors say, “The mathematical roads that this new edition follows are the same as before, but we hope that the ride is considerably smoother”. I share the opinion of the reviewer of the second edition that this book can be recommended as a text for a basic course (the first third of the text), as well as for an advanced course at graduate level.
