| folland: Quantum Field Theory: A Tourist Guide for Mathematicians Gerald B. Folland, 2021-02-03 Quantum field theory has been a great success for physics, but it is difficult for mathematicians to learn because it is mathematically incomplete. Folland, who is a mathematician, has spent considerable time digesting the physical theory and sorting out the mathematical issues in it. Fortunately for mathematicians, Folland is a gifted expositor. The purpose of this book is to present the elements of quantum field theory, with the goal of understanding the behavior of elementary particles rather than building formal mathematical structures, in a form that will be comprehensible to mathematicians. Rigorous definitions and arguments are presented as far as they are available, but the text proceeds on a more informal level when necessary, with due care in identifying the difficulties. The book begins with a review of classical physics and quantum mechanics, then proceeds through the construction of free quantum fields to the perturbation-theoretic development of interacting field theory and renormalization theory, with emphasis on quantum electrodynamics. The final two chapters present the functional integral approach and the elements of gauge field theory, including the Salam–Weinberg model of electromagnetic and weak interactions. |

| folland: Introduction to Partial Differential Equations Gerald B. Folland, 2020-05-05 The second edition of Introduction to Partial Differential Equations, which originally appeared in the Princeton series Mathematical Notes, serves as a text for mathematics students at the intermediate graduate level. The goal is to acquaint readers with the fundamental classical results of partial differential equations and to guide them into some aspects of the modern theory to the point where they will be equipped to read advanced treatises and research papers. This book includes many more exercises than the first edition, offers a new chapter on pseudodifferential operators, and contains additional material throughout. The first five chapters of the book deal with classical theory: first-order equations, local existence theorems, and an extensive discussion of the fundamental differential equations of mathematical physics. The techniques of modern analysis, such as distributions and Hilbert spaces, are used wherever appropriate to illuminate these long-studied topics. The last three chapters introduce the modern theory: Sobolev spaces, elliptic boundary value problems, and pseudodifferential operators. |

| folland: Justice Miscarried Helena Katz, 2011-06-14 Former bank manager Ronald Dalton never got to watch his three young children grow up. In 1989 he was convicted for a crime that never happened. His wife, Brenda, was later ruled to have choked to death on breakfast cereal not strangled as a pathologist had initially claimed. Dalton’s daughter, Alison, was in kindergarten when he was charged with second-degree murder in 1988. He attended her high school graduation on June 26, 2000, two days after his conviction was finally overturned. Behind the proud facade of Canada’s criminal justice system lie the shattered lives of the people unjustly caught within its web. Justice Miscarried tells the heartwrenching stories of twelve innocent Canadians, including David Milgaard, Donald Marshall, Guy Paul Morin, Clayton Johnson, William Mullins-Johnson, and Thomas Sophonow, who were wrongly convicted and the errors in the nations justice system that changed their lives forever. |
| folland: Harmonic Analysis in Phase Space. (AM-122), Volume 122 Gerald B. Folland, 2016-03-02 This book provides the first coherent account of the area of analysis that involves the Heisenberg group, quantization, the Weyl calculus, the metaplectic representation, wave packets, and related concepts. This circle of ideas comes principally from mathematical physics, partial differential equations, and Fourier analysis, and it illuminates all these subjects. The principal features of the book are as follows: a thorough treatment of the representations of the Heisenberg group, their associated integral transforms, and the metaplectic representation; an exposition of the Weyl calculus of pseudodifferential operators, with emphasis on ideas coming from harmonic analysis and physics; a discussion of wave packet transforms and their applications; and a new development of Howe's theory of the oscillator semigroup. |

| folland: The Royal Air Force at Home Ian Watson, 2010-06-19 Military public relations endeavors ultimately seek to build a sense of common interests and aims, and so generally foster good relations with the people they defend, and there in ensure a stable society. The armed forces when engaging on any public relations exercise, have traditionally sought to provide an entertaining spectacle. For years this has been typified by parades, bands, mock battles, drill displays and other relevant feats of military prowess which have captured the imagination of the public and inspired potential recruits. The 20th Century brought a new dimension to the field of warfare and subsequently added a new strand to the fabric of public ceremony and displays by the armed forces. That new dimension was the arrival of powered flight.Display flying began within five years of the Wright Brothers making their milestone first flight. The first events staged in Britain which centered on demonstrations by flying machines, were organized by the town councils of Blackpool and Doncaster and were held within days of each other in October 1909. 1920 was the year that the first of the famed and legendary Hendon Air Pageants was staged, and this is where military air shows traditionally began. The Hendon Displays were organized and staged by the still fledging Royal Air Force and it was probably due in no small part to the prestige and spectacle of this fresh new dimension of military pageantry, together with other like events held at RAF airfields through the next two decades, that the very existence of the RAF was saved from the threat of abolition. The history of the RAF's commitment (one that compares almost uniquely with other air forces) toward display flying through the years after World War II has now come of age. This account of their record in this often overlooked but then again traditional field of military customs, describes and illustrates the major public RAF events since 1920. |
| folland: The Economics of Health and Health Care Sherman Folland, Allen C. Goodman, Miron Stano, 2017-06-26 Folland, Goodman, and Stano’s bestselling The Economics of Health and Health Care text offers the market-leading overview of all aspects of Health Economics, teaching through core economic themes, rather than concepts unique to the health care economy. The Eighth Edition of this key textbook has been revised and updated throughout, and reflects changes since the implementation of the Affordable Care Act (ACA). In addition to its revised treatment of health insurance, the text also introduces the key literature on social capital as it applies to individual and public health, as well as looking at public health initiatives relating to population health and economic equity, and comparing numerous policies across Western countries, China, and the developing world. It provides up-to-date discussions on current issues, as well as a comprehensive bibliography with over 1,100 references. Extra material and teaching resources are now also available through the brand new companion website, which provides full sets of discussion questions, exercises, presentation slides, and a test bank. This book demonstrates the multiplicity of ways in which economists analyze the health care system, and is suitable for courses in Health Economics, Health Policy/Systems, or Public Health, taken by health services students or practitioners. |
| folland: Long-Term Climate Monitoring by the Global Climate Observing System Thomas R. Karl, 2012-12-06 Is the climate warming? Is the hydrological cycle intensifying? Is the climate becoming more variable or extreme? Is the chemical composition of the atmosphere changing? Is the solar irradiance constant? Answers to these questions are fundamental to understanding, predicting, and assessing climate on time scales ranging from weeks to a century. Atmospheric, oceanic, and environmental scientists have primarily relied on an ad-hoc collection of disparate environmental observational and data management systems to address these problems. But these systems were not designed to measure climate variations and, as a result, changes and variations of the earth system during the instrumental climate record is far from unequivocal. This book develops a framework from which a Global Climate Observing System, currently being discussed in international forums, can be implemented to monitor changes and variations of climate. Audience: Administrators, policy makers, professionals, graduate students, and others interested in learning how we can ensure a long-term climate record for application to national economic development and understanding ecosystem dynamics. |

In the setting of a general measure space, every concept is defined precisely and every theorem is presented with a clear and complete proof with all the relevant details. Counter-examples are provided to show that certain conditions in the hypothesis of a theorem cannot be simply dropped.The dependence of a theorem on earlier theorems is explicitly indicated in the proof, not only to facilitate reading but also to delineate the structure of the theory. The precision and clarity of presentation make the book an ideal textbook for a graduate course in real analysis while the wealth of topics treated also make the book a valuable reference work for mathematicians. |

| folland: Aspects Of Representation Theory And Noncommutative Harmonic Analysis Jean H Gallier, Jocelyn Quaintance, 2025-01-17 This book presents the theory of harmonic analysis for noncommutative compact groups. If G is a commutative locally compact group, there is a well-understood theory of harmonic analysis as discussed in Aspects of Harmonic Analysis on Locally Compact Abelian Groups. If G is not commutative, things are a lot tougher. In the special case of a compact group, there is a deep interplay between analysis and representation theory which was first discovered by Hermann Weyl and refined by Andre Weil. This book presents these seminal results of Weyl and Weil.Starting with the basics of representations theory, it presents the famous Peter-Weyl theorems and discusses Fourier analysis on compact groups. This book also introduces the reader to induced representations of locally compact groups, induced representations of G-bundles, and the theory of Gelfand pairs. A special feature is the chapter on equivariant convolutional neural networks (CNNs), a chapter which shows how many of the abstract concepts of representations, analysis on compact groups, Peter-Weyl theorems, Fourier transform, induced representations are used to tackle very practical, modern-day problems. |
| folland: Hardy Inequalities on Homogeneous Groups Michael Ruzhansky, Durvudkhan Suragan, 2019-07-02 This open access book provides an extensive treatment of Hardy inequalities and closely related topics from the point of view of Folland and Stein's homogeneous (Lie) groups. The place where Hardy inequalities and homogeneous groups meet is a beautiful area of mathematics with links to many other subjects. While describing the general theory of Hardy, Rellich, Caffarelli-Kohn-Nirenberg, Sobolev, and other inequalities in the setting of general homogeneous groups, the authors pay particular attention to the special class of stratified groups. In this environment, the theory of Hardy inequalities becomes intricately intertwined with the properties of sub-Laplacians and subelliptic partial differential equations. These topics constitute the core of this book and they are complemented by additional, closely related topics such as uncertainty principles, function spaces on homogeneous groups, the potential theory for stratified groups, and the potential theory for general Hörmander's sums of squares and their fundamental solutions. This monograph is the winner of the 2018 Ferran Sunyer i Balaguer Prize, a prestigious award for books of expository nature presenting the latest developments in an active area of research in mathematics. As can be attested as the winner of such an award, it is a vital contribution to literature of analysis not only because it presents a detailed account of the recent developments in the field, but also because the book is accessible to anyone with a basic level of understanding of analysis. Undergraduate and graduate students as well as researchers from any field of mathematical and physical sciences related to analysis involving functional inequalities or analysis of homogeneous groups will find the text beneficial to deepen their understanding. |
| folland: A Companion to Analysis Thomas William Körner, 2004 This book not only provides a lot of solid information about real analysis, it also answers those questions which students want to ask but cannot figure how to formulate. To read this book is to spend time with one of the modern masters in the subject. --Steven G. Krantz, Washington University, St. Louis One of the major assets of the book is Korner's very personal writing style. By keeping his own engagement with the material continually in view, he invites the reader to a similarly high level of involvement. And the witty and erudite asides that are sprinkled throughout the book are a real pleasure. --Gerald Folland, University of Washingtion, Seattle Many students acquire knowledge of a large number of theorems and methods of calculus without being able to say how they hang together. This book provides such students with the coherent account that they need. A Companion to Analysis explains the problems which must be resolved in order to obtain a rigorous development of the calculus and shows the student how those problems are dealt with. Starting with the real line, it moves on to finite dimensional spaces and then to metric spaces. Readers who work through this text will be ready for such courses as measure theory, functional analysis, complex analysis and differential geometry. Moreover, they will be well on the road which leads from mathematics student to mathematician. Able and hard working students can use this book for independent study, or it can be used as the basis for an advanced undergraduate or elementary graduate course. An appendix contains a large number of accessible but non-routine problems to improve knowledge and technique. |
| folland: Moonlight Over England The Story of One Nightfighter Pilot Eric P. Donald, 2013 I came across an old photo recently and pondered the people in it. The person in the centre was my late brother, Norman G. Donald of the RAF. The other figures in the photo I do not know, though I suspect they were his flight instructors at North Battleford, Canada. The photo bears my brother's script KING-PINS ALL!--N. BATTLEFORD. After qualifying as a pilot, he sailed back to England and was posted to RAF Hunsdon just north of London in 1942. He was soon flying Douglas Havocs and Bristol Beaufighters. Night fighters were a new school of defence, but it was hopeless finding enemy aircraft in the dark. The Turbinlite device was fitted to the Beaufighters and Havocs, and the idea was to find the enemy somehow, guided by ground control using heavy ground radar units (too heavy to carry in aircraft), turn on the Turbinlite searchlight, and illuminate the enemy aircraft. A single-engined Hurricane fighter flying alongside then shot down the enemy aircraft. It did help to see the target as this same sky was full of thousands of Allied aircraft, all trying to avoid each other. |

| folland: RAF at the Crossroads Greg Baughen, 2021-05-26 The events of 1942 marked a pivotal year in the history of British air power. For more than two decades the theory that long-range bombing could win wars had dominated British defense policy. The vast majority of warplanes ordered for the RAF were designed either to bomb enemy cities or stop the enemy from bombing British cites. Conventional armies and the air forces that supported them were seen as an outmoded way of waging war. During 1941 evidence began to mount that British policy was wrong. It had become clear the RAF’s bomber offensive against Germany had, until that point, achieved very little. Meanwhile, the wars raging in Europe, Africa and Asia were being decided not by heavy bombers, but by armies and their supporting tactical air forces. Britain had never had the resources to build a large army as well as a strategic bomber fleet; it had always had to make a choice. Now it seemed the country might have made the wrong choice. For the first time since 1918 Britain began thinking seriously about a different way of fighting wars. Was it too late to change? Was a strategic bombing campaign the only option open to Britain? Could the United Kingdom help its Soviet ally more by invading France as Stalin so vehemently demanded? Could this be done in 1942? Looking further ahead, was it time to begin the development of an entirely new generation of warplanes to support the Army? Should the RAF have specialist ground attack aircraft and air superiority fighters? The answers to these questions, which are all explored here by aviation historian Greg Baughen, would help shape the development of British air power for decades to come. |

| folland: Heroes and Landmarks of British Aviation Richard Edwards, Peter J. Edwards, 2012-10-24 Heroes and Landmarks of British Aviation tells the dramatic story of a world leading aviation industry, from the sweat and grease of the workshop, to the board rooms and government nationalisations that ultimately fashioned its destiny.The heroes are Britains most innovative aviation pioneers and their aircraft, the men and women who persevered to be the first into the air, to fly the fastest, the highest and the furthest. This broad and highly accessible books ranges from the first man to fly across the English Channel from England to France to the development of the Spitfire and from the disastrous R101 airship to the development of the jet engine and ultimately the worlds first supersonic airliner.Each chapter looks at a different aviation pioneer and the flying machines that they designed, their engineering landmarks, their triumphs in the air and on occasion their disasters too. The book explores the great air races that were won and lost, the government contracts and political short-sightedness that cut short the development of leading aircraft designs and many of the dramatic air raids and sea battles from the First World War to the Falklands and the Middle East.Many of the industrys most prominent names are profiled, including Ernest Willows, the Short brothers, Geoffrey de Havilland, Vincent Richmond, George White, Thomas Sopwith, Harry Hawker, RJ Mitchell, Herbert Smith, Charles Rolls, Henry Royce, Reginald Pierson, Alliott Verdon-Roe, Frederick Handley Page, Robert Watson-Watt, Robert Blackburn and Frank Whittle.Behind the personal stories are the histories of the aircraft companies that these pioneers created, from those that went bankrupt to those that lasted the test of time and have become indivisible from British aviation folklore, such names as Sopwith, Handley Page, Avro, Supermarine, Blackburn, Bristol, Fairey and Rolls-Royce. The book covers the mergers and acquisitions that led to the creation of two major aircraft manufacturers, Hawker Siddeley Group and the British Aircraft Corporation, and how barely two decades later, before the century was out, they were nationalised to form British Aerospace. |
| folland: Harmonic and Complex Analysis in Several Variables Steven G. Krantz, 2017-09-20 Authored by a ranking authority in harmonic analysis of several complex variables, this book embodies a state-of-the-art entrée at the intersection of two important fields of research: complex analysis and harmonic analysis. Written with the graduate student in mind, it is assumed that the reader has familiarity with the basics of complex analysis of one and several complex variables as well as with real and functional analysis. The monograph is largely self-contained and develops the harmonic analysis of several complex variables from the first principles. The text includes copious examples, explanations, an exhaustive bibliography for further reading, and figures that illustrate the geometric nature of the subject. Each chapter ends with an exercise set. Additionally, each chapter begins with a prologue, introducing the reader to the subject matter that follows; capsules presented in each section give perspective and a spirited launch to the segment; preludes help put ideas into context. Mathematicians and researchers in several applied disciplines will find the breadth and depth of the treatment of the subject highly useful. |

| folland: Weather and Climate Extremes Thomas R. Karl, Neville Nicholls, Anver Ghazi, 2013-03-09 Are extreme weather events becoming more common? How do extreme weather events impact society? These are critical questions that must be examined as we confront the possibility that the world will experience a change in climate over the next century. Much of the research in climatology over the past decade has focused on potential changes in long- term averages of temperature, precipitation and other factors. However, it is becoming increasingly clear that changes in average values will be accompanied by changes in extreme events. Furthermore, extreme weather events will impact society to a greater extent as people around the world continue to locate in more hazard-prone areas such as coastal zones. This book represents a major step forwards in developing a comprehensive set of information about changes in extreme events by providing a review of the problems in data availability, quality and analysis that make deriving a clear picture of world-wide changes in extreme events so difficult. Audience: The book is intended for policy-makers, professionals, graduate students and others interested in learning how extreme weather events have changed, and how they impact society both now and in the future. |

| folland: British Aircraft Manufacturers Since 1909 Peter G. Dancey, 2017-01-24 British Aircraft Manufacturers since 1909 traces one hundred years of the British aviation industry, its history, origins, mergers and takeovers. It details the evolution of the British aviation industry and is an epitaph to household famous names such as Armstrong-Whitworth, de Havilland, Chadwick, Claude-Graham White, Sopwith, A. V. Roe, Mitchell, Hawker, Handley Page, Petter and Fairey to name but a few. Of more recent times, the likes of Sidney Camm, Hooker and Hooper, all of whom, made VTOL more than just a dream, are also covered in astonishing and exhausting detail. Of the major firms, most at some time or other have been absorbed, merged or reorganised to form a single conglomerate, BAe Systems and Rolls-Royce are chronicled from the outset to the mighty companies they are today. Only PBN-Britten Norman - who on several occasions escaped extinction due to financial difficulties - and Westland, now part of AgustaWestland, and Short Bros of Northern Ireland remain independent, although even the latter, are part of Canadian, Bombardier Co. British Aircraft Manufacturers since 1909 tells the complete and enthralling story of how Britain ruled the world in terms of manufacturing and aircraft design from nimble but fragile biplanes and majestic airliners that united the world to the advanced bombers and fighters of today. |

| folland: Hawker's Early Jets Christopher Budgen, 2022-02-10 A study of the British manufacturer’s efforts to get its Hunter aircraft into service following World War II. On September 2 1947, Hawker Aircraft Ltd figuratively and literally took to the air with their first jet design, the P.1040. Conceived in the latter days of the Second World War, and developed in the straitened times of post-war austerity, the aircraft allowed Hawker to explore the new technology before moving on to more ambitious programs. Rejected by the Royal Air Force, subsequent development of the aircraft allowed the Royal Navy to find in it a useful role at sea. As this project slowly wound its way through the government bureaucracy against a background of national insolvency, Hawker continued their research into more potent forms of jet travel with their first swept wing aircraft, the P.1052, their first rocket powered example, the P.1072, and, finally, the sleek, all swept P.1081. These essentially research aircraft gave the company the experience and expertise it required to produce a powerful, transonic fighter with which to equip the RAF for the defense of the UK and other friendly nations at a time when the Cold War threatened to engulf the world in a truly global nuclear conflict. That aircraft, the P.1067 Hunter first flew in 1951 and was, at the time, the fastest fighter in the world as evinced by gaining the World Airspeed Record in 1953 prior to entry into RAF service; at a stroke revolutionizing the potential of the UK’s air arm. Such was the haste with which this occurred that many teething problems remained to be resolved, as detailed here, but eventually the aircraft would become the day fighter of choice for many of the world’s air forces and remain in service for decades to come. |
