Rings Around London

Each ring is illustrated with one or more black and white photograph, with 500 superb colour photos of the most important pieces. Major trends in ring design are outlined, and explanations and anecdotes are given on many of the individual rings. Supplementary images provide additional visual reference for the historical context. This deluxe book introduces the finest, most exhaustive private collection of finger rings in the world: the Hashimoto Collection. Organised chronologically by culture, it begins with the Ancient Mediterranean World, and progresses

London Orbital is Iain Sinclair's voyage of discovery into the unloved outskirts of the city. Encircling London like a noose, the M25 is a road to nowhere, but when Iain Sinclair sets out to walk this asphalt loop - keeping within the 'acoustic footprints' - he is determined to find out where the journey will lead him. Stumbling upon converted asylums, industrial and retail parks, ring-fenced government institutions and lost villages, Sinclair discovers a Britain of the fringes, a landscape consumed by developers. London Orbital charts this extraordinary trek and round trip of the soul, revealing the country as you've never seen it before. 'My book of the year. Sentence for sentence, there is no more interesting writer at work in English'John Lanchester, Daily Telegraph 'A magnum opus, my book of the year. I urge you to read it. In fact, if you're a Londoner and haven't read it by the end of next year, I suggest you leave'Will Self, Evening Standard 'A journey into the heart of darkness and a fascinating snapshot of who we are, lit by Sinclair's vivid prose. I'm sure it will be read fifty years from now'J. G. Ballard, Observer Iain Sinclair is the author of Downriver (winner of the James Tait Black Memorial Prize and the Encore Award); Landor's Tower; White Chappell, Scarlet Tracings; Lights Out for the Territory; Lud Heat; Rodinsky's Room (with Rachel Lichtenstein); Radon Daughters; London Orbital, Dining on Stones, Hackney, that Rose-Red Empire and Ghost Milk.

This book is an introduction to the theory of rings and modules that goes beyond what one normally obtains in a graduate course in abstract algebra. In addition to the presentation of standard topics in ring and module theory, it also covers category theory, homological algebra and even more specialized topics like injective envelopes and proj

Proving that a polynomial ring in one variable over a field is a principal ideal domain can be done by means of the Euclidean algorithm, but this does not extend to more variables. However, if the variables are not allowed to commute, giving a free associative algebra, then there is a generalization, the weak algorithm, which can be used to prove that all one-sided ideals are free. This book presents the theory of free ideal rings (firs) in detail. Particular emphasis is placed on rings with a weak algorithm, exemplified by free associative algebras. There is also a full account of localization which is treated for general rings but the features arising in firs are given special attention. Each section has a number of exercises, including some open problems, and each chapter ends in a historical note.

"The book is like a dream you want to last forever" (Roberta Silman, The New York Times Book Review), now with a gorgeous new cover by the famed designer Peter Mendelsund A masterwork of W. G. Sebald, now with a gorgeous new cover by the famed designer Peter Mendelsund The Rings of Saturn—with its curious archive of photographs—records a walking tour of the eastern coast of England. A few of the things which cross the path and mind of its narrator (who both is and is not Sebald) are lonely eccentrics, Sir Thomas Browne’s skull, a matchstick model of the Temple of Jerusalem, recession-hit seaside towns, wooded hills, Joseph Conrad, Rembrandt’s "Anatomy Lesson," the natural history of the herring, the massive bombings of WWII, the dowager Empress Tzu Hsi, and the silk industry in Norwich. W.G. Sebald’s The Emigrants (New Directions, 1996) was hailed by Susan Sontag as an "astonishing masterpiece perfect while being unlike any book one has ever read." It was "one of the great books of the last few years," noted Michael Ondaatje, who now acclaims The Rings of Saturn "an even more inventive work than its predecessor, The Emigrants."

Ancient finger rings made of base metals and low-grade silver alloys are increasingly being unearthed and sold through a growing assortment of marketplaces worldwide. Reference material on ancient rings has focused mainly on historic and "high-end" pieces--the precious metals and stones of royalty and the wealthy--while little has been written on the evaluation of common rings. This guide describes their composition, structure and imagery, thus providing merchants, collectors and researchers with a comprehensive reference on these ancient artifacts that, until now, have gone unexamined.

Ideal for graduate students and researchers, this book presents a unified treatment of the central notions of integral closure.

A guide to the characters, places, landscapes, and artifacts of Middle-earth, profiles hobbits, men, elves, dwarves, wizards, and orcs.

This is a reprinted edition of a work that was considered the definitive account in the subject area upon its initial publication by J. Wiley & Sons in 1987. It presents, within a wider context, a comprehensive account of noncommutative Noetherian rings. The author covers the major developments from the 1950s, stemming from Goldie's theorem and onward, including applications to group rings, enveloping algebras of Lie algebras, PI rings, differential operators, and localization theory. The book is not restricted to Noetherian rings, but discusses wider classes of rings where the methods apply more generally. In the current edition, some errors were corrected, a number of arguments have been expanded, and the references were brought up to date. This reprinted edition will continue to be a valuable and stimulating work for readers interested in ring theory and its applications to other areas of mathematics.
