This book investigates the high degree of symmetry that lies hidden in integrable systems. To that end, differential equations arising from classical mechanics, such as the KdV equation and the KP equations, are used here by the authors to introduce the notion of an infinite dimensional transformation group acting on spaces of integrable systems. Chapters discuss the work of M. Sato on the algebraic structure of completely integrable systems, together with developments of these ideas in the work of M. Kashiwara. The text should be accessible to anyone with a knowledge of differential and...

This work is concerned with combinatorial aspects arising in the theory of exactly solvable models and representation theory. Developments in integrable models reveal an unexpected link between representation theory and statistical mechanics through combinatorics. For example, Young tableaux, which describe the basis of irreducible representations, appear in the Bethe Ansatz method in quantum spin chains as labels for the eigenstates of Hamiltonians. this text presents results and ideas from three viewpoints: representation theory; integrable models; and combinatorics.

'MathPhys Odyssey 2001' will serve as an excellent reference text for mathematical physicists and graduate students in a number of areas.; Kashiwara/Miwa have a good track record with both SV and Birkhauser.

Taking into account the various criss-crossing among mathematical subject, Physical Combinatorics presents new results and exciting ideas from three viewpoints; representation theory, integrable models, and combinatorics. This work is concerned with combinatorial aspects arising in the theory of exactly solvable models and representation theory. Recent developments in integrable models reveal an unexpected link between representation theory and statistical mechanics through combinatorics.

This volume is dedicated to Barry M. McCoy on the occasionofhis sixtieth birthday. Barry McCoy has led the research on integrable models in statistical mechanics and quantumfieldtheoryfor morethan 30years. Hisbook, cowrittenwithT.T.Wu, The Two dimensional/sing Model, (HarvardUniversity)containsallthebasic resultsontheIsing model obtained by the early 1970s. However, McCoy'sjointpaper with Wu, Tracy and Barouch, Spin-spin correlation functions for the two-dimensional/sing model: Exact results in the scaling region (Physical Review B13, 316-374, 1976), was a giant step beyond the book.
