Baxter R.Exactly Solved Models in Statistical Mechanics 3ed 1989 torrent

Textbook in PDF format

Several two-dimensional lattice models in statistical mechanics have been solved exactly, notably the Ising, spherical, ice eight-vertex and hard-hexagon models. Their solutions are presented here, and it is shown how they give invaluable information on critical behaviour, particularly on universality. Emphasis is laid on the development of the calculational techniques and methods from one model to the next, and on various unifying features such as the star-triangle relation
