Robert B Israel 1979 Princeton, New Jersey: Princeton University Press Ixxxv + 167 pp price £10.40 (£4.40 paperback) The main text concerns the systematic use of hard theorems in convexity to prove the existence of spontaneous magnetisation in the isotropic Heisenberg spin model, and other lattice systems. This book will become a classic, not least because of the superb, less formal, introduction by A S Wightman.
