Topics in Commutative Ring Theory - John J. Watkins - Bog - Princeton University Press - Plusbog.dk

Topics in Commutative Ring Theory - John J. Watkins - Bog - Princeton University Press - Plusbog.dk

Topics in Commutative Ring Theory is a textbook for advanced undergraduate students as well as graduate students and mathematicians seeking an accessible introduction to this fascinating area of abstract algebra. Commutative ring theory arose more than a century ago to address questions in geometry and number theory. A commutative ring is a set-such as the integers, complex numbers, or polynomials with real coefficients--with two operations, addition and multiplication. Starting from this simple definition, John Watkins guides readers from basic concepts to Noetherian rings-one of the most important classes of commutative rings--and beyond to the frontiers of current research in the field. Each chapter includes problems that encourage active reading--routine exercises as well as problems that build technical skills and reinforce new concepts. The final chapter is devoted to new computational techniques now available through computers. Careful to avoid intimidating theorems and proofs whenever possible, Watkins emphasizes the historical roots of the subject, like the role of commutative rings in Fermat''s last theorem. He leads readers into unexpected territory with discussions on rings of continuous functions and the set-theoretic foundations of mathematics. Written by an award-winning teacher, this is the first introductory textbook to require no prior knowledge of ring theory to get started. Refreshingly informal without ever sacrificing mathematical rigor, Topics in Commutative Ring Theory is an ideal resource for anyone seeking entry into this stimulating field of study.

The Cambridge Companion to Wagner's Der Ring des Nibelungen - - Bog - Cambridge University Press - Plusbog.dk

The Cambridge Companion to Wagner's Der Ring des Nibelungen - - Bog - Cambridge University Press - Plusbog.dk

The Companion is an essential, interdisciplinary tool for those both familiar and unfamiliar with Wagner''s Ring. It opens with a concise introduction to both the composer and the Ring, introducing Wagner as a cultural figure, and giving a comprehensive overview of the work. Subsequent chapters, written by leading Wagner experts, focus on musical topics such as ''leitmotif'', and structure, and provide a comprehensive set of character portraits, including leading players like Wotan, Brünnhilde, and Siegfried. Further chapters look to the mythological background of the work and the idea of the Bayreuth Festival, as well as critical reception of the Ring, its relationship to Nazism, and its impact on literature and popular culture, in turn offering new approaches to interpretation including gender, race and environmentalism. The volume ends with a history of notable stage productions from the world premiere in 1876 to the most recent stagings in Bayreuth and elsewhere.

King Solomon's Ring - Konrad Lorenz - Bog - Taylor & Francis Ltd - Plusbog.dk

King Solomon's Ring - Konrad Lorenz - Bog - Taylor & Francis Ltd - Plusbog.dk

Solomon, the legend goes, had a magic ring which enabled him to speak to the animals in their own language. Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon''s Ring , the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

Ring of Fire - - Bog - Taylor & Francis Ltd - Plusbog.dk

Ring of Fire - - Bog - Taylor & Francis Ltd - Plusbog.dk

The ring of fire stands for the life cycle of both the universe and each individual being: the circular dance of nature in the eternal process of creation and destruction. At the same time, the light radiated by the ring of flames symbolizes eternal wisdom and transcendental illumination. -J.E. Cirlot. A Dictionary of Symbols The circular form in which the group is seated symbolizes its unity, connectedness, and cohesion as well as its microcosmic relation to the larger world of human evolution, culture, and the life cycle. Foulkes, Bion, and others have identified primitive layers of affect and object relations where universal collective themes and early infantile object relations are re-experienced and repeated in the meeting place for healing called the therapy group. In this context, very profound emotions and energies are released which have deep implications for change and growth, provided the therapist can manage and respond to them effectively. This book brings together a collection of new and original contributions to an understanding of primitive object relations and intensely critical emotional states which present the maximum challenge to the group psychotherapist: the ring of fire. An international group of colleagues, based primarily in Great Britain and the United States, address areas of special interest to them and to which they have devoted considerable research and therapeutic effort. They provide insights into the dynamics of these issues and guide the therapist in the management and interpretation of the group events as they unfold. While much has been written on primitive group states, the information is scattered throughout many journals and books and all too often does not address the practical problems faced by the group therapist in Practical terms. Furthermore, there have been significant developments in affect theory and object relations theory which have yet to be assimilated sufficiently into the theory and technique of group psychotherapy. This book attempts to reduce that gap as it concentrates on the relevance of concepts to treatment in accordance with Kurt Lewin''s maxim, There is nothing so practical as a good theory. Ring of Fire will be invaluable to group psychotherapy supervisors, beginning and experienced group therapists, students and supervisers of group psychotherapy and group dynamics, and organizational consultants who utilize group dynamics principles in their work. Victor L. Schermer is a clinical psychologist in private practice in Philadelphia. He is Executive Director of the Study Group for Contemporary Psychoanalytic Process and Director of the Institute for the Study of Human Conflict. Malcolm Pines was, until his recent retirement, Consultant Psychiatrist at the Tavistock Clinic, London and is a member of the Group-Analytic Practice.

The Ring and the Cross - - Bog - Fairleigh Dickinson University Press - Plusbog.dk

The Ring and the Cross - - Bog - Fairleigh Dickinson University Press - Plusbog.dk

The conversation, sometimes heated, about the influence of Christianity on the writings of J.R.R. Tolkien has a long history. What has been lacking is a forum for a civilized discussion about the topic, as well as a chronological overview of the major arguments and themes that have engaged scholars about the impact of Christianity on Tolkien''s oeuvre, with particular reference to The Lord of the Rings. The Ring and the Cross addresses these two needs through an articulate and authoritative analyses of Tolkien''s Roman Catholicism and the role it plays in understanding his writings. The volume''s contributors deftly explain the kinds of interpretations put forward and evidence marshaled when arguing for or against religious influence. The Ring and the Cross invites readers to draw their own conclusions about a subject that has fascinated Tolkien enthusiasts since the publication of his masterpiece, The Lord of the Rings.

Ring Lardner and the Other - Douglas Robinson - Bog - Oxford University Press - Plusbog.dk

Ring Lardner and the Other - Douglas Robinson - Bog - Oxford University Press - Plusbog.dk

Ring Lardner was one of the most popular figures of the early twentieth century - newspaper columnist, sports writer, short story writer and personality - yet he has received little attention from scholars. Douglas Robinson''s new book examines the writings of a critically neglected American writer; it also uses Lardner as the basis for a theoretical inquiry into language and literature, and a study of men and masculinity at the turn of the century.

Ring of Liberation - J. Lowell Lewis - Bog - The University of Chicago Press - Plusbog.dk

Ring of Liberation - J. Lowell Lewis - Bog - The University of Chicago Press - Plusbog.dk

Based on eighteen months of intensive participant-observation, Ring of Liberation offers both an in-depth description of capoeira--a complex Afro-Brazilian martial art that combines feats of great strength and athleticism with music and poetry--and a pioneering synthetic approach to the analysis of complex cultural performance. Capoeira originated in early slave culture and is practiced widely today by urban Brazilians and others. At once game, sport, mock combat, and ritualized performance, it involves two players who dance and "battle" within a ring of musicians and singers. Stunning physical performances combine with music and poetry in a form as expressive in movement as it is in word. J. Lowell Lewis explores the convergence of form and content in capoeira. The many components and characteristics of this elaborate black art form--for example, competing genre frameworks and the necessary fusion of multiple modes of expression--demand, Lewis feels, to be given "body" as well as "voice."In response, he uses Peircean semiotics and recent work in discourse and performance theory to map the connections between physical, musical, and linguistic play in capoeira and to reflect on the general relations between semiotic systems and the creation and recording of cultural meaning.

Non-hausdorff Completion, A: The Abelian Category Of C-complete Left Modules Over A Topological Ring - Saul Lubkin - Bog - World Scientific Publishing

Non-hausdorff Completion, A: The Abelian Category Of C-complete Left Modules Over A Topological Ring - Saul Lubkin - Bog - World Scientific Publishing

This book introduces entirely new invariants never considered before, in homological algebra and commutative (and even non-commutative) algebra. The C -completion C ( M ), and higher C -completions, C n ( M ), are defined for an arbitrary left module M over a topological ring A . Spectral sequences are defined that use these invariants. Given a left module over a topological ring A , under mild conditions the usual Hausdorff completion: M ^ can be recovered from the C -completion C ( M ), by taking the quotient module by the closure of {0}. The new invariants and tools in this book are expected to be used in the study of p-adic cohomology in algebraic geometry; and also in the study of p-adic Banach spaces — by replacing the cumbersome "complete tensor product" of p-adic Banach spaces, with the more sophisticated "C-complete tensor product", discussed in this book. It is also not unlikely that the further study of these new invariants may well develop into a new branch of abstract mathematics - connected with commutative algebra, homological algebra, and algebraic topology.

The Poetical Works of Robert Browning Volume IX: The Ring and the Book, Books IX-XII - - Bog - Oxford University Press - Plusbog.dk

The Poetical Works of Robert Browning Volume IX: The Ring and the Book, Books IX-XII - - Bog - Oxford University Press - Plusbog.dk

The Ring and the Book, Browning''s 21,000 line epic, is widely regarded as his masterpiece. This is the third, and final, volume of the Oxford edition covering this work, comprising the monologue of Johannes-Baptista Bottinius, and then the glowing conclusion to the work as a whole: the monologues of Pope Innocent XII and of Guido in his prison-cell prior to execution, and then the witty, ironic envoi of Book XII. The commentary in this edition contains a wealth of new contextual material that illuminates Browning''s work in sometimes surprising ways. The copy text of 1888-9, the final edition of Browning''s lifetime, has been scrupulously examined, both in relation to compositors'' errors, and Browning''s own final corrections to the text: eighty-nine emendations to accidentals, and nineteen emendations to substantives, produce a text as near as possible to Browning''s final intentions. Appendix A presents previously unknown source material, concerning the ''cadaver synod'' of 897, from Browning''s father''s historical notebooks. The Afterword gives a fresh view of the real history of the Franceschini murder case, based on new research in the archives in Arezzo.

ULF Waves’ Interaction with Cold and Thermal Particles in the Inner Magnetosphere - Jie Ren - Bog - Springer Verlag, Singapore - Plusbog.dk

ULF Waves’ Interaction with Cold and Thermal Particles in the Inner Magnetosphere - Jie Ren - Bog - Springer Verlag, Singapore - Plusbog.dk

This thesis focuses on ULF (Ultra-low-frequency) waves'' interaction with plasmasphere particles and ring current ions in the inner magnetosphere. It first reports and reveals mutual effect between ULF waves and plasmasphere using Van Allen Probes data. The differences and similarities of different ring current ions interacting with ULF waves are extensively explored using Cluster data, which provides a potential explanation for O + -dominated ring current during the magnetic storms. Furthermore, this thesis finds a method to study the phase relationship between ULF waves and drift-bounce resonant particles, and proposes that the phase relationship can be used to diagnose the parallel structure of standing wave electric field and energy transfer directions between waves and particles. The findings in this thesis can significantly promote our understanding of ULF waves'' role in the dynamics of inner magnetosphere.
