Lectures on the Infrared Structure of Gravity and Gauge Theory

"Strominger is the main architect behind the recent revival of the study of asymptotic symmetries in gravity and gauge theory. Pedagogical and effective, his timely and exciting approach takes readers to the forefront of new developments."-Hirosi Ooguri, California Institute of Technology "This clear and concise book describes the infrared structure of gauge theories and gravity. It contains many new and interesting results. An invaluable reference, its solid scholarship will survive the test of time and make a significant contribution to the field."-Juan Maldacena, Institute for Advanced Study "In the 1950s, Feynman and others brilliantly solved the ultraviolet problems in electromagnetics by renormalization, but the infrared properties of gauge theory were felt to be trivial and were neglected. However, Strominger's book shows that they are a rich field that may well hold the resolution of the black hole information paradox."-Stephen Hawking, University of Cambridge and author of A Brief History of Time "The infrared behavior of gauge theories and gravity has been a source of fascination for more than fifty years. This book beautifully lays out exciting developments connecting this research with modern ideas in quantum gravity, leading to a unified understanding of classic results and a host of deep new discoveries. A must-read for all theorists working in fundamental physics."-Nima Arkani-Hamed, Institute for Advanced Study "Strominger is a master physicist and instructor. In this wonderful new book, he patiently and clearly takes the reader on a journey a half century in the making, laying the quantum mechanical foundations for gauge theories and gravity. Students and practitioners alike have a rare opportunity to be guided by a prime mover of modern physics whose pedagogical skills are second to none."-Brian Greene, Columbia University
