In July 2009 Germany hosted the 50th International Mathematical Olympiad (IMO). For the very first time the number of participating countries exceeded 100, with 104 countries from all continents. Celebrating the 50th anniversary of the IMO provides an ideal opportunity to look back over the past five decades and to review its development to become a worldwide event. This book is a report about the 50th IMO as well as the IMO history. A lot of data about all the 50 IMOs are included. We list the most successful contestants, the results of the 50 Olympiads and the 112 countries that have ever taken part. It is impressive to see that many of the world’s leading research mathematicians were among the most successful IMO participants in their youth. Six of them gave presentations at a special celebration: Bollobás, Gowers, Lovász, Smirnov, Tao and Yoccoz. This book is aimed at students in the IMO age group and all those who have interest in this worldwide leading competition for highschool students.
Aimed at undergraduate mathematics and computer science students, this book is an excellent introduction to a lot of problems of discrete mathematics. It discusses a number of selected results and methods, mostly from areas of combinatorics and graph theory, and it uses proofs and problem solving to help students understand the solutions to problems. Numerous examples, figures, and exercises are spread throughout the book.
This graduate-level text provides a thorough grounding in the representation theory of finite groups over fields and rings. The book provides a balanced and comprehensive account of the subject, detailing the methods needed to analyze representations that arise in many areas of mathematics. Key topics include the construction and use of character tables, the role of induction and restriction, projective and simple modules for group algebras, indecomposable representations, Brauer characters, and block theory. This classroom-tested text provides motivation through a large number of worked examples, with exercises at the end of each chapter that test the reader's knowledge, provide further examples and practice, and include results not proven in the text. Prerequisites include a graduate course in abstract algebra, and familiarity with the properties of groups, rings, field extensions, and linear algebra.
One of the most effective ways to stimulate students to enjoy intellectual efforts is the scientific competition. In 1894 the Hungarian Mathematical and Physical Society introduced a mathematical competition for high school students. The success of high school competitions led the Mathematical Society to found a college level contest, named after Miklós Schweitzer. The problems of the Schweitzer Contests are proposed and selected by the most prominent Hungarian mathematicians. This book collects the problems posed in the contests between 1962 and 1991 which range from algebra, combinatorics, theory of functions, geometry, measure theory, number theory, operator theory, probability theory, topology, to set theory. The second part contains the solutions. The Schweitzer competition is one of the most unique in the world. The experience shows that this competition helps to identify research talents. This collection of problems and solutions in several fields in mathematics can serve as a guide for many undergraduates and young mathematicians. The large variety of research level problems might be of interest for more mature mathematicians and historians of mathematics as well.
(In)digestion in Literature and Film: A Transcultural Approach is a collection of essays spanning diverse geographic areas such as Brazil, Eastern Europe, France, Ireland, Italy, Japan, Mexico, South Korea, Taiwan and the United States. Despite this geographic variance, they all question disordered eating practices represented in literary and filmic works. The collection ultimately redefines disorder, removing the pathology and stigma assigned to acts of non-normative eating. In so doing, the essays deem taboo practices of food consumption, rejection and avoidance as expressions of resistance and defiance in the face of restrictive sociocultural, political, and economic normativities. As a result, disorder no longer equates to "out of order", implying a sense of brokenness, but is instead envisioned as an act against the dominant of order of operations. The collection therefore shifts critical focus from the eater as the embodiment of disorder to the problematic norms that defines behaviors as such.
Plutôt qu'un traitement monographique, ce numéro propose une approche multidisciplinaire axée sur le thème du temps et de l'histoire. Divers aspects du cinéma hongrois de 1945 à nos jours sont abordés : l'attrait puis le rejet du stalinisme, les années 60, l'après-1989.
Although the end of the Cold War was greeted with great enthusiasm by people in the East and the West, the ensuing social and especially economic changes did not always result in the hoped-for improvements in people's lives. This led to widespread disillusionment that can be observed today all across Eastern Europe. Not simply a longing for security, stability, and prosperity, this nostalgia is also a sense of loss regarding a specific form of sociability. Even some of those who opposed communism express a desire to invest their new lives with renewed meaning and dignity. Among the younger generation, it surfaces as a tentative yet growing curiosity about the recent past. In this volume scho...
