Mathematical Physics 12th

This text contains proceedings of the 12th International Congress on Mathematical Physics which was held in Brisbane, Australia by the International Association of Mathematical Physics in July, 1997. The triannual conference brought forth important findings from researchers around the world. Topics covered include the numerical solution of the English equations, duality, strings and supergravity, analyticity of invariant tori as functions of the perturbation parameter for nonanalytic perturbations, planner algebras, and conformal algebras.
