Perspectives on spin glasses Presenting and developing the theory of spin glasses as a prototype for complex systems this book is a rigorous and up to date introduction to their properties. The book combines a mathematical description with a physical insight of spin glass models. Topics covered include the physical origins of those models and their treatment with replica theory; mathematical properties like correlation inequalities and their use in the thermodynamic limit theory; main exact solutions of the mean field models and their probabilistic structures; and the theory of the structural properties of the spin glass phase such as stochastic stability and the overlap identities. Finally a detailed account is given of the recent numerical simulation results and properties including overlap equivalence ultrametricity and decay of correlations.
