This textbook introduces the representation theory of algebras by focusing on two of its most important aspects: the Auslander–Reiten theory and the study of the radical of a module category. It starts by introducing and describing several characterisations of the radical of a module category, then presents the central concepts of irreducible morphisms and almost split sequences, before providing the definition of the Auslander–Reiten quiver, which encodes much of the information on the module category. It then turns to the study of endomorphism algebras, leading on one hand to the definition of the Auslander algebra and on the other to tilting theory. The book ends with selected properties of representation-finite algebras, which are now the best understood class of algebras. Intended for graduate students in representation theory, this book is also of interest to any mathematician wanting to learn the fundamentals of this rapidly growing field. A graduate course in non-commutative or homological algebra, which is standard in most universities, is a prerequisite for readers of this book.
This is the first of a two-volume set that provides a modern account of the representation theory of finite dimensional associative algebras over an algebraically closed field. The subject is presented from the perspective of linear representations of quivers and homological algebra. The treatment is self-contained and provides an elementary and up-to-date introduction to the subject using quiver-theoretical techniques and the theory of almost split sequences as well as tilting theory and the use of integral quadratic forms. Much of this material has never appeared before in book form. The book is primarily addressed to graduate students starting research in the representation theory of algebras, but it will also be of interest to mathematicians in other fields. The text includes many illustrative examples and a large number of exercises at the end of each of the ten chapters. Proofs are presented in complete detail, making the book suitable for courses, seminars, and self-study. Book jacket.
This first part of a two-volume set offers a modern account of the representation theory of finite dimensional associative algebras over an algebraically closed field. The authors present this topic from the perspective of linear representations of finite-oriented graphs (quivers) and homological algebra. The self-contained treatment constitutes an elementary, up-to-date introduction to the subject using, on the one hand, quiver-theoretical techniques and, on the other, tilting theory and integral quadratic forms. Key features include many illustrative examples, plus a large number of end-of-chapter exercises. The detailed proofs make this work suitable both for courses and seminars, and for self-study. The volume will be of great interest to graduate students beginning research in the representation theory of algebras and to mathematicians from other fields.

Porous and Complex Flow Structures in Modern Technologies represents a new approach to the field, considering the fundamentals of porous media in terms of the key roles played by these materials in modern technology. Intended as a text for advanced undergraduates and as a reference for practicing engineers, the book uses the physics of flows in porous materials to tie together a wide variety of important issues from such fields as biomedical engineering, energy conversion, civil engineering, electronics, chemical engineering, and environmental engineering. Thus, for example, flows of water and oil through porous ground play a central role in energy exploration and recovery (oil wells, geothermal fluids), energy conversion (effluents from refineries and power plants), and environmental engineering (leachates from waste repositories). Similarly, the demands of miniaturization in electronics and in biomedical applications are driving research into the flow of heat and fluids through small-scale porous media (heat exchangers, filters, gas exchangers). Filters, catalytic converters, the drying of stored grains, and a myriad of other applications involve flows through porous media. By providing a unified theoretical framework that includes not only the traditional homogeneous and isotropic media but also models in which the assumptions of representative elemental volumes or global thermal equilibrium fail, the book provides practicing engineers the tools they need to analyze complex situations that arise in practice. This volume includes examples, solved problems and an extensive glossary of symbols.

In Pragmatism in Islamic Law, Ibrahim presents a detailed history of Sunni legal pluralism and the ways in which it was employed to accommodate the changing needs of society. Since the formative period of Islamic law, jurists have debated whether it is acceptable for a law to be selected based on its utility, rather than weighing conflicting articulations of the law to determine the most likely expression of the divine will. Virtually unanimous opposition to the utilitarian approach, referred to as “pragmatic eclecticism,” emerged among early Islamic jurists. However, due to a host of changing institutional and socioeconomic transformations, a trend toward the legitimization of pragmatic eclecticism arose in the thirteenth century. Subsequently, the Mamluk authorities institutionalized this pragmatism when Sultan Baybars appointed four chief judges representing the four Sunni schools in Cairo in 1265 CE. After a brief attempt to reverse Mamluk pluralism by imposing the Hanafi school in the sixteenth century, Egypt’s new rulers, the Ottomans, embraced this pluralistic pragmatism. In examining over a thousand cases from three seventeenth- and eighteenthcentury Egyptian courts, Ibrahim traces the internal logic of pragmatic eclecticism under the Ottomans. An array of archival sources documents the manner in which Egyptian society’s subaltern classes navigated Sunni legal pluralism as a tool to avoid more austere legal doctrines. The ensuing portrait challenges the assumption made by many modern historians that the utilitarian approaches adopted by nineteenth- and twentieth-century Muslim reformers constituted a clear rupture with early Islamic legal history. In contrast, many of the legal strategies exercised in Egypt’s partial codification of family law in the twentieth century were rooted in premodern Islamic jurisprudence.

This book investigates the relationship between the self and screen in the digital age, and examines how the notion of the self is re-negotiated and curated online. The chapters examine the production of the self in postmodernity through digital platforms by employing key concepts of ubiquity, the everyday, disembodiment and mortality. It locates self-production through ubiquitous imaging of the self and our environments with and through mobile technologies and in terms of its ‘embeddedness’ in our everyday lives. In this innovative text, Yasmin Ibrahim explores technology’s co-location on our corporeal body, our notions of domesticity and banality, our renewed relationship with the screen and our enterprise with capital as well as the role of desire in the formation of the self. The result is a richly interdisciplinary volume that seeks to examine the formation of the self online, through its renewed negotiations with personalised technologies and with the emergence of social networking sites.

The most lavishly decorated tomb in ancient Egypt was constructed for Queen Nefertari, wife of Rameses the Great. The Getty Conservation Institute has been instrumental in the effort to restore the tomb’s magnificent wall paintings, and in the fall of 1992, to mark the project’s completion, an exhibition was held at the Getty Museum. The exhibition included a model of the tomb and full-scale reproductions of the wall paintings. The publication describes the conservation work (including before and after photographs), outlines the life of Nefertari, and places the tomb in the context of Egyptian art history.
