The goal of this book is to present local class field theory from the cohomo logical point of view, following the method inaugurated by Hochschild and developed by Artin-Tate. This theory is about extensions-primarily abelian-of ´´local´´ (i.e., complete for a discrete valuation) fields with finite residue field. For example, such fields are obtained by completing an algebraic number field; that is one of the aspects of ´´localisation´´. The chapters are grouped in ´´parts´´. There are three preliminary parts: the first two on the general theory of local fields, the third on group coho mology. Local class field theory, strictly speaking, does not appear until the fourth part. Here is a more precise outline of the contents of these four parts: The first contains basic definitions and results on discrete valuation rings, Dedekind domains (which are their ´´globalisation´´) and the completion process. The prerequisite for this part is a knowledge of elementary notions of algebra and topology, which may be found for instance in Bourbaki. The second part is concerned with ramification phenomena (different, discriminant, ramification groups, Artin representation). Just as in the first part, no assumptions are made here about the residue fields. It is in this setting that the ´´norm´´ map is studied; I have expressed the results in terms of ´´additive polynomials´´ and of ´´multiplicative polynomials´´, since using the language of algebraic geometry would have led me too far astray.

Quantum field theory, which started with Paul Dirac´s work shortly after the discovery of quantum mechanics, has produced an impressive and important array of results. Quantum electrodynamics, with its extremely accurate and well-tested predictions, and the standard model of electroweak and chromodynamic (nuclear) forces are examples of successful theories. Field theory has also been applied to a variety of phenomena in condensed matter physics, including superconductivity, superfluidity and the quantum Hall effect. The concept of the renormalization group has given us a new perspective on field theory in general and on critical phenomena in particular. At this stage, a strong case can be made that quantum field theory is the mathematical and intellectual framework for describing and understanding all physical phenomena, except possibly for a quantum theory of gravity. Quantum Field Theory: A Modern Perspective presents Professor Nair´s view of certain topics in field theory loosely knit together as it grew out of courses on field theory and particle physics taught at Columbia University and the City College of CUNY. The first few chapters, up to Chapter 12, contain material that generally goes into any course on quantum field theory, although there are a few nuances of presentation which readers may find to be different from other books. This first part of the book can be used for a general course on field theory, omitting, perhaps, the last three sections in Chapter 3, the last two in Chapter 8 and sections 6 and 7 in Chapter 10. The remaining chapters cover some of the more modern developments over the last three decades, involving topological and geometrical features. The introduction given to the mathematical basis of this part of the discussion is necessarily brief and should be accompanied by books on the relevant mathematical topics as indicated in the bibliography. Professor Nair also concentrates on developments pertinent to a better understanding of the standard model. There is no discussion of supersymmetry, supergravity, developments in field theory inspired by string theory, etc. There is also no detailed discussion of the renormalization group. Each of these topics would require a book in its own right to do justice to the topic. Quantum Field Theory: A Modern Perspective serves as a portal to so many more topics of detailed and ongoing research, referring readers to more detailed treatments for many specific topics. The book also contains extensive references, providing readers a more comprehensive perspective on the literature and the historical development of the subject. V. Parameswaran Nair is Professor of Physics at City College of The City University of New York (CUNY). Professor Nair has held Visiting Professorships at The Abdus Salam International Center for Theoretical Physics, Rockefeller University, Institute for Advanced Study at Princeton, and Massachusetts Institute of Technology.

This short book approaches quantum field theory via the study of a selection of important papers in QED, electroweak theory and QCD. It places emphasis on Fermi and Bethe´s original papers involving the non-covariant formulation of QED; their formalism is transparent and played an historically important role in the development of QFT. Although the field has changed dramatically since their time, it is prudent to understand Bethe´s use of renormalization of mass in the calculation of the Lamb shift before embarking on a study of renormalization group techniques and running coupling constants that underpin concepts in QCD. Renormalization is an underlying theme in the development of quantum field theory, and Ken Wilson´s work and the advent of effective field theory is also addressed. The modern view of renormalization is contrasted with the initial concerns of Dirac and others who were opposed to renormalization techniques. This book is aimed at graduate students who have mastered quantum mechanics and special relativity, and are about to embark on a study of QED, and QFT in general. It provides an invaluable framework for a reader to subsequently work through standard QFT textbooks.

Like any books on a subject as vast as this, this book has to have a point-of-view to guide the selection of topics. Naber takes the view that the rekindled interest that mathematics and physics have shown in each other of late should be fostered, and that this is best accomplished by allowing them to cohabit. The book weaves together rudimentary notions from the classical gauge theory of physics with the topological and geometrical concepts that became the mathematical models of these notions. The reader is asked to join the author on some vague notion of what an electromagnetic field might be, to be willing to accept a few of the more elementary pronouncements of quantum mechanics, and to have a solid background in real analysis and linear algebra and some of the vocabulary of modern algebra. In return, the book offers an excursion that begins with the definition of a topological space and finds its way eventually to the moduli space of anti-self-dual SU(2) connections on S4 with instanton number -1.

Jeffs Views provide witty, insightful, and thought-provoking looks into the life of a modern scientist. From starting off to letting go, Gottfried (Jeff) Schatz leads us through the trials and triumphs of scientific life. With his tongue firmly in his cheek, and his humour always intact, the Austrian essayist leads us through the confusing and seemingly insurmountable hill that is the career path of European scientists. In addition to giving useful insights into how to get funding, give seminars, and still find time to make that leading edge scientific discovery, Jeff explores the philosophical dimensions of recent biological breakthroughs such as the sequencing of the human genome, the evolution of sensory receptors, and cellular suicide. Gottfried Schatz is one of the worlds leading scientists in the field of bioenergetics and mitochondria biology. Born in a small Austrian village, he started his scientific career at the University of Graz, and ended it as President of the Swiss Science and Technology Council. With stints as a violinist in Austrian opera houses, professorships in the USA and Switzerland, and numerous prestigious awards along the way, Jeff is a true European, whose unique, and often controversial, viewpoints are appreciated by scientists and politicians alike. These essays look at science from a very personal angle often critical, sometimes sad, but always with excitement, wonder, and admiration. It is hoped that they will make you look at science with a slightly different view. *Witty, insightful, and thought-provoking looks into life of a modern scientist *Provides useful insights on how to get funding, give seminars, and still find time to make thatscientific discovery *Explores recent breakthroughs in science: genome sequencing, sensory receptor evolution, and cellular suicide

This is the first introductory textbook on quantum field theory to be written from the point of view of condensed matter physics. As such, it presents the basic concepts and techniques of statistical field theory, clearly explaining how and why they are integrated into modern (and classical) field theory, and includes the latest developments. Written by an expert in the field, with a broad experience in teaching and training, it manages to present such substantial topics as phases and phase transitions or solitons and instantons in an accessible and concise way. Divided into two parts, the first covers fundamental physics and the mathematics background needed by students in order to enter the field, while the second part discusses applications of quantum field theory to a few basic problems. The emphasis here lies on how modern concepts of quantum field theory are embedded in these approaches, and also on the limitations of standard quantum field theory techniques in facing ´real´ physics problems. Throughout, there are numerous end-of-chapter problems, and a free solutions manual is available for lecturers.
