Non-Perturbative Field Theory

Providing A New Perspective On Quantum Field Theory This Book Gives A Pedagogical Exposition Of Non-Perturbative Methods In Relativistic Quantum Field Theory And Introduces The Reader To Modern Research In Theoretical Physics. After Describing Non-Perturbative Methods In Detail It Uses These Methods To Explore Two-Dimensional And Four-Dimensional Gauge Dynamics. 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 In Particular Are Thoroughly Described. Published Originally In 2010 This Title Has Been Reissued As An Open Access Publication On Cambridge Core.
