Description
Book SynopsisThis 1999 book investigates the high degree of symmetry that lies hidden in integrable systems. 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.
Trade Review' ... this charming book can be recommended to anybody interested in the modern development in the mathematics arising from mathematical physics.' EMS
