Non-Perturbative Field Theory

Providing a new perspective on quantum field theory this book gives a pedagogical and up-to-date exposition of non-perturbative methods in relativistic quantum field theory and introduces the reader to modern research work in theoretical physics. It describes in detail non-perturbative methods in quantum field theory and explores two- dimensional and four- dimensional gauge dynamics using those methods. The book concludes with a summary emphasizing the interplay between two- and four- dimensional gauge theories. Aimed at graduate students and researchers this book covers topics from two-dimensional conformal symmetry affine Lie algebras solitons integrable models bosonization and 't Hooft model to four-dimensional conformal invariance integrability large N expansion Skyrme model monopoles and instantons. Applications first to simple field theories and gauge dynamics in two dimensions and then to gauge theories in four dimensions and quantum chromodynamics (QCD) in particular are thoroughly described. Review '… Non-Perturbative Field Theory will have enduring value as a comprehensive reference.' Contemporary Physics Book Description Pedagogical exposition providing a new perspective on relativistic quantum field theory for graduate students and researchers.
