Sommario/riassunto

Preface to the Second Edition It has been eight years since the first edition of Combinatorics of Permutations was published. All parts of the subject went through significant progress during those years. Therefore, we had to make some painful choices as to what to include in the new edition of this book. First, there is a new chapter to this edition, Chapter 9, which is devoted to sorting algorithms whose original motivation comes from molecular biology. This very young part of combinatorics is known for its easily stated and extremely difficult



problems which sometimes can be solved using deep techniques from remote-looking parts of mathematics. We decided to discuss three sorting algorithms in detail. Second, half of the existing chapters, namely Chapters 1, 3, 4, and 6 have been significantly changed or extended. Chapter 1 has a new section on Alternating Permutations, while Chapter 3 has new material on multivariate applications of the Exponential Formula. In Chapter 4, which discusses pattern avoidance, several important results, some in the text, some in the exercises, have been improved. Chapter 6, discussing some probabilistic aspects of permutations, now covers the concept of asymptotically normal distributions. Third, all chapters have an extended Exercises section and an extended Problems Plus section. The latter often contains results from the last eight years. Exercises marked with a (+) sign are thought to be more difficult than average, while exercises marked with a (-) sign are thought to be easier. The book does not assume previous knowledge of combinatorics above the level of an introductory undergraduate course--

Sommario/riassunto

Sujet de vifs débats politiques, élément crucial de la gestion publique, la protection de l’environnement est devenue une préoccupation majeure au cours des dernières décennies - non seulement au Canada mais partout dans le monde. Les questions de pollution de l’air et de l’eau, des pluies acides, de la protection de la couche d’ozone, des substances toxiques et des rejets en mer sont de plus en plus discutées dans les sphères gouvernementales et dans la population en général.  Dans cet ouvrage, les auteurs étudient les tendances actuelles en gestion de l’environnement et leurs impacts sur le plan humain, mettant l’accent sur deux aspects : les principaux défis que posent les nouveaux enjeux environnementaux à la gestion des affaires publiques et les nouvelles approches destinées à relever ces défis. Ils y passent en



revue les principales tendances en environnement et s’interrogent sur les développements possibles au cours des prochaines décennies. Ils identifient en outre les principaux défis qui se présentent à la société canadienne (incluant notamment les défis en matière de politiques publiques) et définissent enfin les recherches prioritaires à entreprendre.
