The description of solids at a microscopic level is complex, involving the interaction of a huge number of its constituents, such as ions or electrons. It is impossible to solve the corresponding many-body problems analytically or numerically, although much insight can be gained from the analysis of simplified models. An important example is the Hubbard model, which describes interacting electrons in narrow energy bands, and which has been applied to problems as diverse as high-Tc superconductivity, band magnetism, and the metal-insulator transition. This book presents a coherent, self-contained account of the exact solution of the Hubbard model in one dimension. The early chapters will be accessible to beginning graduate students with a basic knowledge of quantum mechanics and statistical mechanics. The later chapters address more advanced topics, and are intended as a guide for researchers to some of the more topical results in the field of integrable models.

"The joint expertise of the authors on the subject is formidable. The influence of their intimate familiarity with the material is visible throughout the book. The bibliography is extensive and will be a useful tool for those interested in the original publications. Short of asking an expert, there is no better way to access the huge body of work accumulated over decades by a large number of authors. Every physics and chemistry library should have a copy of this book, and many individual researchers want to have a copy on their shelves, too."
