Most of the interesting and difficult problems in statistical mechanics arise when the constituent particles of the system interact with each other with pair or multipartiele energies. The types of behaviour which occur in systems because of these interactions are referred to as cooperative phenomena giving rise in many cases to phase transitions. This book and its companion volume (Lavis and Bell 1999, referred to in the text simply as Volume 1) are princi pally concerned with phase transitions in lattice systems. Due mainly to the insights gained from scaling theory and renormalization group methods, this subject has developed very rapidly over the last thirty years. ' In our choice of topics we have tried to present a good range of fundamental theory and of applications, some of which reflect our own interests. A broad division of material can be made between exact results and ap proximation methods. We have found it appropriate to inelude some of our discussion of exact results in this volume and some in Volume 1. Apart from this much of the discussion in Volume 1 is concerned with mean-field theory. Although this is known not to give reliable results elose to a critical region, it often provides a good qualitative picture for phase diagrams as a whole. For complicated systems some kind of mean-field method is often the only tractable method available. In this volume our main concern is with scaling theory, algebraic methods and the renormalization group.

A soft cover reprint of "The Pancios from Galicia." The original book by George Bell was published in hard cover in 1993. It follows the lives and families of the three Pancio brothers who emigrated from the town of Tylawa, Galicia in Ruthenian Austria-Frank, Paul and John, and the brother and sister they left behind-Daniel and Anna. John, the last to arrive, passed through Ellis Island, New York, in 1914. The book commemorates the 100th anniversary of the birth of John's first daughter, Eva Pancio Plano. Family trees, index, and appendix of details of family's life and work in Galicia, Homer Hill and North Olean, New York and Auburn, New York. 402 pages. 8.5 x 11 black and white with color cover.
