Random Walks, Critical Phenomena, and Triviality in Quantum Field Theory

by Alan D. Sokal J. Rg Fr Hlich Roberto Fernandez, Alan Sokal

The subject of this book is equilibrium statistical mechanics, in particular the theory of critical phenomena, and quantum field theory. The central theme is the use of random-walk representations as a tool to derive correlation inequalities. The consequences of these inequalities for critical-exponent theory and the triviality question in quantum field theory are expounded in detail. The book contains some previously unpublished results. It addresses both the researcher and the graduate student in modern statistical mechanics and quantum field theory.
