A co-publication of the AMS and International Press of Boston

This volume contains the proceedings of the 1999 International Conference on Differential Equations and Mathematical Physics. The contributions selected for this volume represent some of the most important presentations by scholars from around the world on developments in this area of research. The papers cover topics in the general area of linear and nonlinear differential equations and their relation to mathematical physics, such as multiparticle Schrödinger operators, stability of matter, relativity theory, fluid dynamics, spectral and scattering theory including inverse problems.

Titles in this series are co-published with International Press of Boston, Inc., Cambridge, MA.

#### Readership

Researchers and graduate students interested in differential equations and mathematical physics.
