This book highlights important developments on artinian modules over group rings of generalized nilpotent groups. Along with traditional topics such as direct decompositions of artinian modules, criteria of complementability for some important modules, and criteria of semisimplicity of artinian modules, it also focuses on recent advanced results on these matters.
The influence of different gomomorphic images on the structure of a group is one of the most important and natural problems of group theory. The problem of describing a group with all its gomomorphic images known, i.e. reconstructing the whole thing using its reflections, seems especially natural and promising. This theme has a history that is almost a half-century long. The authors of this book present well-established results as well as newer, contemporary achievements in this area from the common integral point of view. This view is based on the implementation of module theory for solving group problems. Evidently, this approach requires investigation of some specific types of modules: infinite simple modules and just infinite modules (note that every infinite noetherian module has either an infinite simple factor-module or a just infinite factor-module). This book will therefore be useful for group theorists as well as ring and module theorists. Also, the level, style, and presentation make the book easily accessible to graduate students.
The series «Duisburg Papers on Research in Language and Culture» presents a forum for linguistic research on the interrelationship between language and culture. The series is interdisciplinary in nature and consists of monographs and collections of papers. The main purpose of the editors is to initiate a dialogue between linguistic science and neighboring disciplines such as sociology, anthropology, semiotics, literary studies, and intercultural communication.
This volume presents the lecture notes from the authors’ three summer courses offered during the program “Automorphisms of Free Groups: Geometry, Topology, and Dynamics,” held at the Centre de Recerca Matemàtica (CRM) in Bellaterra, Spain. The first two chapters present the basic tools needed, from formal language theory (regular and context-free languages, automata, rewriting systems, transducers, etc) and emphasize their connections to group theory, mostly relating to free and virtually-free groups. The material covered is sufficient to present full proofs of many of the existing interesting characterizations of virtually-free groups. In turn, the last chapter comprehensively describes Bonahon’s construction of Thurston’s compactification of Teichmüller space in terms of geodesic currents on surfaces. It also includes several intriguing extensions of the notion of geodesic current to various other, more general settings.
This comprehensive survey of Spain’s history looks at the major political, social, and economic changes that took place from the end of the Civil War to the beginning of the twenty-first century. A thorough introduction to post-Civil War Spain, from its development under Franco and subsequent transition to democracy up to the present day Tusell was a celebrated public figure and historian. During his lifetime he negotiated the return to Spain of Picasso’s Guernica, was elected UCD councillor for Madrid, and became a respected media commentator before his untimely death in 2005 Includes a biography and political assessment of Francisco Franco Covers a number of pertinent topics, including fascism, isolationism, political opposition, economic development, decolonization, terrorism, foreign policy, and democracy Provides a context for understanding the continuing tensions between democracy and terrorism, including the effects of the 2004 Madrid Bombings
The study of institutions, a core concept in comparative politics, has produced many rich and influential theories on the economic and political effects of institutions, yet it has been less successful at theorizing their origins. In Fixing Democracy, Javier Corrales develops a theory of institutional origins that concentrates on constitutions and levels of power within them. He reviews numerous Latin American constituent assemblies and constitutional amendments to explore why some democracies expand rather than restrict presidential powers and why this heightened presidentialism discourages democracy. His signal theoretical contribution is his elaboration on power asymmetries. Corrales determines that conditions of reduced power asymmetry make constituent assemblies more likely to curtail presidential powers, while weaker opposition and heightened power asymmetry is an indicator that presidential powers will expand. The bargain-based theory that he uses focuses on power distribution and provides a more accurate variable in predicting actual constitutional outcomes than other approaches based on functionalism or ideology. While the empirical focus is Latin America, Fixing Democracy contributes a broadly applicable theory to the scholarship both institutions and democracy.
The Spanish Arcadia analyzes the figure of the shepherd in the sixteenth- and seventeenth-century Spanish imaginary, exploring its centrality to the discourses on racial, cultural, and religious identity. Drawing on a wide range of documents, including theological polemics on blood purity, political treatises, manuals on animal husbandry, historiography, paintings, epic poems, and Spanish ballads, Javier Irigoyen-García argues that the figure of the shepherd takes on extraordinary importance in the reshaping of early modern Spanish identity. The Spanish Arcadia contextualizes pastoral romances within a broader framework and assesses how they inform other cultural manifestations. In doing so, Irigoyen-García provides incisive new ideas about the social and ethnocentric uses of the genre, as well as its interrelation with ideas of race, animal husbandry, and nation building in early modern Spain.
The Enciclopedia de Linguistica Hispánica provides comprehensive coverage of the major and subsidiary fields of Spanish linguistics. Entries are extensively cross-referenced and arranged alphabetically within three main sections: Part 1 covers linguistic disciplines, approaches and methodologies. Part 2 brings together the grammar of Spanish, including subsections on phonology, morphology, syntax and semantics. Part 3 brings together the historical, social and geographical factors in the evolution of Spanish. Drawing on the expertise of a wide range of contributors from across the Spanish-speaking world the Enciclopedia de Linguistica Hispánica is an indispensable reference for undergraduate and postgraduate students of Spanish, and for anyone with an academic or professional interest in the Spanish language/Spanish linguistics.
The Essentials in Cytopathology book series fulfills the need for an easy-to-use and authoritative synopsis of site specific topics in cytopathology. These guide books fit into the lab coat pocket and are ideal for portability and quick reference. Each volume is heavily illustrated with a full color art program, while the text follows a user-friendly outline format. Central Nervous System Intraoperative Cytopathology covers the full spectrum of benign and malignant conditions of the CNS with emphasis on common disorders. The volume is heavily illustrated and contains useful algorithms that guide the reader through the differential diagnosis of common and uncommon entities encountered in the field of intraoperative neuro-cytopathology. Central Nervous System Intraoperative Cytopathology is a valuable quick reference for pathologists, cytopathologists, and fellows and trainees dealing with this exigent field.
