Spin glasses This collection of state of the art review papers witten by leading experts in the field covers the topic from a wide variety of angles. The topics covered are mean field spin glasses including a pedagogical account of Talagrands proof of the Parisi solution short range spin glasses emphasizing the open problem of the relevance of the mean field theory for lattice models and the dynamics of spin glasses in particular the problem of ageing in mean field models. The book will serve as a concise introduction to the state of the art of spin glass theory usefull to both graduate students and young researchers as well as to anyone curious to know what is going on in this exciting area of mathematical physics.
