Non-perturbative Methods In Two-dimensional Quantum Field Theory

Rothe, Klaus D, Abdalla, Maria Cristina Batoni, Abdalla, Elcio

This book is a survey of methods used in the study of two-dimensional models in quantum field theory as well as applications of these theories in physics. It covers the subject since the first model, studied in the fifties, up to modern developments in string theories, and includes exact solutions, non-perturbative methods of study, and nonlinear sigma models.
