The worthy purpose of this text is to provide a complete, self-contained development of the trace formula and theta inversion formula for SL(2, Z i])\SL(2, C). Unlike other treatments of the theory, the approach taken here is to begin with the heat kernel on SL(2, C) associated to the invariant Laplacian, which is derived using spherical inversion. The heat kernel on the quotient space SL(2, Z i])\SL(2, C) is arrived at through periodization, and further expanded in an eigenfunction expansion. A theta inversion formula is obtained by studying the trace of the heat kernel. Following the author's previous work, the inversion formula then leads to zeta functions through the Gauss transform.

This new Reader aims to guide students through some of the key readings on the subject of terrorism and political violence.

In an age when there is more written about terrorism than anyone can possibly read in a lifetime, it has become increasingly difficult for students and scholars to navigate the literature. At the same time, courses and modules on terrorism studies are developing at a rapid rate. To meet this challenge, this wide-ranging Reader seeks to equip the aspiring student, based anywhere in the world, with a comprehensive introduction to the study of terrorism. Containing many of the most influential and groundbreaking studies from the world s leading experts, drawn from several academic disciplines, this volume is the essential companion for any student of terrorism and political violence.

The Reader, which starts with a detailed Introduction by the editors, is divided into seven sections, each of which contains a short introduction as well as a guide to further reading and student discussion questions:

• Terrorism in Historical Context
• Definitions
• Understanding and Explaining Terrorism
• Terrorist Movements
• Terrorist Behaviour
• Counterterrorism
• Current and Future Trends in Terrorism.

This Reader will be essential reading for students of Terrorism and Political Violence, and highly recommended for students of Security Studies, War and Conflict Studies and Political Science in general, as well as for practitioners in the field of counter-terrorism and homeland security.

Projective duality is a very classical notion naturally arising in various areas of mathematics, such as algebraic and differential geometry, combinatorics, topology, analytical mechanics, and invariant theory, and the results in this field were until now scattered across the literature. Thus the appearance of a book specifically devoted to projective duality is a long-awaited and welcome event.

Projective Duality and Homogeneous Spaces covers a vast and diverse range of topics in the field of dual varieties, ranging from differential geometry to Mori theory and from topology to the theory of algebras. It gives a very readable and thorough account and the presentation of the material is clear and convincing. For the most part of the book the only prerequisites are basic algebra and algebraic geometry.

This book will be of great interest to graduate and postgraduate students as well as professional mathematicians working in algebra, geometry and analysis.

This book explores the theory and application of locally nilpotent derivations. It provides a unified treatment of the subject, beginning with sixteen First Principles on which the entire theory is based. These are used to establish classical results, such as Rentschler 's Theorem for the plane, right up to the most recent results, such as Makar-Limanov 's Theorem for locally nilpotent derivations of polynomial rings. The book also includes a wealth of pexamples and open problems.

Over last decades low-dimensional materials are in focus of physics and chemistry as well as of material and other natural sciences. Like Vitaly Ginzburg has foreseen 30 years ago, low dimensionality offers physical phenomena and properties unseen in three-dimensional world. To see how thin ?lms and monomolecular layers realize such a prediction it suf?ces only to observe intensity of research devoted to recently synthesized graphene. Still, quasi-one-dimensional compounds are over long period established as the origin of the most important and most interesting discoveries of material science and solid state physics. To mention only deoxyribonucleic acid, the most important molecule in nature, and diversity of nanotubes and nanowires, the cornerstones of the present and future nanotechnology. Line groups, describing symmetry of quasi-one-dimensional materials, offer the deepest insight to their characteristic properties. Underlying many of the laws, they are very useful, but far from simple. This book is intended to explain them, their properties, and their most common applications. In particular, it is important to understand that the line groups are much wider class of symmetries than the well-known rod groups. While the latter describe only translationally periodical objects, line groups include symmetries of incommensurate periodical structures.

This introduction to the representation theory of compact Lie groups follows Herman Weyl 's original approach. It discusses all aspects of finite-dimensional Lie theory, consistently emphasizing the groups themselves. Thus, the presentation is more geometric and analytic than algebraic. It is a useful reference and a source of explicit computations. Each section contains a range of exercises, and 24 figures help illustrate geometric concepts.

Introduces the richness of group theory to advanced undergraduate and graduate students, concentrating on the finite aspects.

Provides a wealth of exercises and problems to support self-study.

Additional online resources on more challenging and more specialised topics can be used as extension material for courses, or for further independent study.

Trust is a crucial facet of social functioning that feeds into our relationships with individuals, groups, and organizations. The Psychology of Interpersonal Trust: Theory and Research examines existing theories, frameworks, and models of trust as well as the methods and designs for examining it. To fully examine how interpersonal trust impacts our lives, Rotenberg reviews the many essential topics trust relates to, including close relationships, trust games, behavioural trust, and trust development. Designed to encourage researchers to recognize the links between different approaches to trust, this book begins with an overview of the different approaches to interpersonal trust and a description of the methods used to investigate it. Following on from this, each chapter introduces a new subtopic or context, including lying, adjustment, socialization, social media, politics, and health. Each subtopic begins with a short monologue (to provide a personal perspective) and covers basic theory and research. Rotenberg's applied focus demonstrates the relevance of interpersonal trust and highlights the issues and problems people face in contemporary society. This is essential reading for students, researchers, and academics in social psychology, especially those with a specific interest in the concept of trust.

In the last ?fteen years two seemingly unrelated problems, one in computer science and the other in measure theory, were solved by amazingly similar techniques from representation theory and from analytic number theory. One problem is the - plicit construction of expanding graphs (-expanders-). These are highly connected sparse graphs whose existence can be easily demonstrated but whose explicit c- struction turns out to be a dif?cult task. Since expanders serve as basic building blocks for various distributed networks, an explicit construction is highly des- able. The other problem is one posed by Ruziewicz about seventy years ago and studied by Banach Ba]. It asks whether the Lebesgue measure is the only ?nitely additive measure of total measure one, de?ned on the Lebesgue subsets of the n-dimensional sphere and invariant under all rotations. The two problems seem, at ?rst glance, totally unrelated. It is therefore so- what surprising that both problems were solved using similar methods: initially, Kazhdan s property (T) from representation theory of semi-simple Lie groups was applied in both cases to achieve partial results, and later on, both problems were solved using the (proved) Ramanujan conjecture from the theory of automorphic forms. The fact that representation theory and automorphic forms have anything to do with these problems is a surprise and a hint as well that the two questions are strongly related."

"The book is largely self-contained...There is a nice introduction to symplectic geometry and a charming exposition of equivariant K-theory. Both are enlivened by examples related to groups...An attractive feature is the attempt to convey some informal wisdom rather than only the precise definitions. As a number of results are] due to the authors, one finds some of the original excitement. This is the only available introduction to geometric representation theory...it has already proved successful in introducing a new generation to the subject." (Bulletin of the AMS)

Hyperbolic Manifolds and Discrete Groups is at the crossroads of several branches of mathematics: hyperbolic geometry, discrete groups, 3-dimensional topology, geometric group theory, and complex analysis. The main focus throughout the text is on the "Big Monster," i.e., on Thurston 's hyperbolization theorem, which has not only completely changes the landscape of 3-dimensinal topology and Kleinian group theory but is one of the central results of 3-dimensional topology.

The book is fairly self-contained, replete with beautiful illustrations, a rich set of examples of key concepts, numerous exercises, and an extensive bibliography and index. It should serve as an ideal graduate course/seminar text or as a comprehensive reference.

This book is a collection of articles, some introductory, some extended surveys, and some containing previously unpublished research, on a range of topics linking infinite permutation group theory and model theory. Topics covered include: oligomorphic permutation groups and omega-categorical structures; totally categorical structures and covers; automorphism groups of recursively saturated structures; Jordan groups; Hrushovski's constructions of pseudoplanes; permutation groups of finite Morley rank; applications of permutation group theory to models of set theory without the axiom of choice. There are introductory chapters by the editors on general model theory and permutation theory, recursively saturated structures, and on groups of finite Morley rank. The book is almost self-contained, and should be useful to both a beginning postgraduate student meeting the subject for the first time, and to an active researcher from either of the two main fields looking for an overview of the subject.

Drawing on psychological and sociological perspectives as well as quantitative and qualitative data, Identity and Interethnic Marriage in the United States considers the ways the self and social identity are linked to the dynamics of interethnic marriage. Bringing together the classic theoretical contributions of George Herbert Mead, Erving Goffman, and Erik Erikson with contemporary research on ethnic identity inspired by Jean Phinney, this book argues that the self and social identity-especially ethnic identity-are reflected in individuals' complex journey from singlehood to interethnic marriage within the United States.

Ce travail en deux volumes donne la preuve de la stabilisation de la formule des trace tordue. Stabiliser la formule des traces tordue est la methode la plus puissante connue actuellement pour comprendre l'action naturelle du groupe des points adeliques d'un groupe reductif, tordue par un automorphisme, sur les formes automorphes de carre integrable de ce groupe. Cette comprehension se fait en reduisant le probleme, suivant les idees de Langlands, a des groupes plus petits munis d'un certain nombre de donnees auxiliaires; c'est ce que l'on appelle les donnees endoscopiques. L'analogue non tordu a ete resolu par J. Arthur et dans ce livre on suit la strategie de celui-ci. Publier ce travail sous forme de livre permet de le rendre le plus complet possible. Les auteurs ont repris la theorie de l'endoscopie tordue developpee par R. Kottwitz et D. Shelstad et par J.-P. Labesse. Ils donnent tous les arguments des demonstrations meme si nombre d'entre eux se tr ouvent deja dans les travaux d'Arthur concernant le cas de la formule des traces non tordue. Ce travail permet de rendre inconditionnelle la classification que J. Arthur a donnee des formes automorphes de carre integrable pour les groupes classiques quasi-deployes, c'etait pour les auteurs une des principales motivations pour l'ecrire. Cette partie contient les preuves de la stabilisation geometrique et de la partie spectrale en particulier de la partie discrete de ce terme, ce qui est le point d'aboutissement de ce sujet.

The aim of this monograph is to give an overview of various classes of in?ni- dimensional Lie groups and their applications, mostly in Hamiltonian - chanics, ?uid dynamics, integrable systems, and complex geometry. We have chosen to present the unifying ideas of the theory by concentrating on speci?c typesandexamplesofin?nite-dimensionalLiegroups. Ofcourse, theselection of the topics is largely in?uenced by the taste of the authors, but we hope thatthisselectioniswideenoughtodescribevariousphenomenaarisinginthe geometry of in?nite-dimensional Lie groups and to convince the reader that they are appealing objects to study from both purely mathematical and more applied points of view. This book can be thought of as complementary to the existing more algebraic treatments, in particular, those covering the str- ture and representation theory of in?nite-dimensional Lie algebras, as well as to more analytic ones developing calculus on in?nite-dimensional manifolds. This monograph originated from advanced graduate courses and mi- courses on in?nite-dimensional groups and gauge theory given by the ?rst author at the University of Toronto, at the CIRM in Marseille, and at the Ecole Polytechnique in Paris in 2001-2004. It is based on various classical and recentresultsthathaveshapedthisnewlyemergedpartofin?nite-dimensional geometry and group theory. Our intention was to make the book concise, relatively self-contained, and useful in a graduate course. For this reason, throughout the text, we have included a large number of problems, ranging from simple exercises to open questions

A fundamental object of study in group theory is the lower central series of groups. Understanding its relationship with the dimension series, which consists of the subgroups determined by the augmentation powers, is a challenging task. This monograph presents an exposition of different methods for investigating this relationship. In addition to group theorists, the results are also of interest to topologists and number theorists. The approach is mainly combinatorial and homological. A novel feature is an exposition of simplicial methods for the study of problems in group theory.

This is the softcover reprint of the English translation of Bourbaki's text Groupes et Algebres de Lie, Chapters 7 to 9. It completes the previously published translations of Chapters 1 to 3 (3-540-64242-0) and 4 to 6 (978-3-540-69171-6) by covering the structure and representation theory of semi-simple Lie algebras and compact Lie groups. Chapter 7 deals with Cartan subalgebras of Lie algebras, regular elements and conjugacy theorems. Chapter 8 begins with the structure of split semi-simple Lie algebras and their root systems. It goes on to describe the finite-dimensional modules for such algebras, including the character formula of Hermann Weyl. It concludes with the theory of Chevalley orders. Chapter 9 is devoted to the theory of compact Lie groups, beginning with a discussion of their maximal tori, root systems and Weyl groups. It goes on to describe the representation theory of compact Lie groups, including the application of integration to establish Weyl's formula in this context. The chapter concludes with a discussion of the actions of compact Lie groups on manifolds. The nine chapters together form the most comprehensive text available on the theory of Lie groups and Lie algebras.

People interact and perform in group settings in all areas of life. Organizations and businesses are increasingly structuring work around groups and teams. Every day, we work in groups such as families, friendship groups, societies and sports teams, to make decisions and plans, solve problems, perform physical tasks, generate creative ideas, and more. Group Performance outlines the current state of social psychological theories and findings concerning the performance of groups. It explores the basic theories surrounding group interaction and development and investigates how groups affect their members. Bernard A. Nijstad discusses these issues in relation to the many different tasks that groups may perform, including physical tasks, idea generation and brainstorming, decision-making, problem-solving, and making judgments and estimates. Finally, the book closes with an in-depth discussion of teamwork and the context in which groups interact and perform. Offering an integrated approach, with particular emphasis on the interplay between group members, the group task, interaction processes and context, this book provides a state-of-the-art overview of social psychological theory and research. It will be highly valuable to undergraduates, graduates and researchers in social psychology, organizational behavior and business.

Business Psychology and Organizational Behaviour introduces principles and concepts in psychology and organizational behaviour with emphasis on relevance and applications. Well organised and clearly written, it draws on a sound theoretical and applied base, and utilizes real-life examples, theories, and research findings of relevance to the world of business and work. The new edition of this best-selling textbook has been revised and updated with expanded and new material, including: proactive personality and situational theory in personality; theory of purposeful work behaviour; emotional and social anxiety in communication; decision biases and errors; and right brain activity and creativity, to name a few. There are numerous helpful features such as learning outcomes, chapter summaries, review questions, a glossary, and a comprehensive bibliography. Illustrations of practice and relevant theory and research also take the reader through individual, group, and organizational perspectives. This is an essential textbook for undergraduates and postgraduates studying psychology and organizational behaviour. What is more, it can be profitably used on degree, diploma, professional, and short courses. It's also likely to be of interest to the reflective practitioner in work organizations.

Zeta functions have been a powerful tool in mathematics over the last two centuries. This book considers a new class of non-commutative zeta functions which encode the structure of the subgroup lattice in infinite groups. It explores the analytic behavior of these functions together with an investigation of functional equations. The book examines many important examples of zeta functions, providing an important database of explicit examples and methods for calculation.

This is an elementary introduction to the representation theory of real and complex matrix groups. The text is written for students in mathematics and physics who have a good knowledge of differential/integral calculus and linear algebra and are familiar with basic facts from algebra, number theory and complex analysis. The goal is to present the fundamental concepts of representation theory, to describe the connection between them, and to explain some of their background. The focus is on groups which are of particular interest for applications in physics and number theory (e.g. Gell-Mann's eightfold way and theta functions, automorphic forms). The reader finds a large variety of examples which are presented in detail and from different points of view.

This book is based on lectures given at a summer school on motivic homotopy theory at the Sophus Lie Centre in Nordfjordeid, Norway, in August 2002. Aimed at graduate students in algebraic topology and algebraic geometry, it contains background material from both of these fields, as well as the foundations of motivic homotopy theory. It will serve as a good introduction as well as a convenient reference for a broad group of mathematicians to this important and fascinating new subject. Vladimir Voevodsky is one of the founders of the theory and received the Fields medal for his work, and the other authors have all done important work in the subject.

Coming Home Your Way offers college and university students returning from an education-abroad experience a wealth of pertinent information, opportunities for meaningful reflection, and practical guidance on making the most of their time abroad. Grounded in research and addressing an array of aspects of education abroad - including intercultural communication, changing relationships, and career impact - Coming Home Your Way will be an invaluable tool for any student planning, experiencing, or returning from a stay abroad. Drawing from theory and research from multiple disciplines, and real-world experiences of students who have studied abroad, the volume addresses key themes critical to understanding reentry, including individual differences in taking in experience, communication patterns and approaches, the reentry transition, the nature of relationships in reentry, bridging reentry and career, and more. Within each chapter are opportunities for self-reflection that allow readers to integrate the ideas presented into their own experience. Compelling short fictional accounts add flavor and detail that bring theory to life. Coming Home Your Way provides a window into the complex experience of intercultural reentry. Reentry from an education-abroad experience can be a period of intense growth, and can feel disruptive and confusing while it's happening. The authors explain and explore these complexities in a conversational style that will engage students, and with the rigor expected by their instructors. Like no other book currently on the market, Coming Home Your Way will give college and university students insight into the challenges and intercultural opportunities that reentry offers.

Ethnocentrism works to reinvigorate the study of ethnocentrism by reconceptualising ethnocentrism as a social, psychological, and attitudinal construct. Using a broad, multidisciplinary approach to ethnocentrism, the book integrates literature from disciplines such as psychology, political science, sociology, anthropology, biology, and marketing studies to create a novel reorganisation of the existing literature, its origins, and its outcomes. Empirical research throughout serves to comprehensively measure the six dimensions of ethnocentrism-devotion, group cohesion, preference, superiority, purity, and exploitativeness-and show how they factor into causes and consequences of ethnocentrism, including personality, values, morality, demographics, political ideology, social factors, prejudice, discrimination, and nationalism. Ethnocentrism is fascinating reading for scholars, researchers, and students in psychology, sociology, and political science.
