This volume emphasizes the interdisciplinary nature of contemporary research in the field of phase transitions, research which involves ideas from nonlinear partial differential equations, asymptotic analysis, numerical computation and experiment. Topics covered include the treatment of scaling laws that describe the coarsening or ripening behavior observed during the later stages of phase transitions; novel numerical methods for treating interface dynamics; the mathematical description of geometric models of interface dynamics; determination of the governing equations and interfacial boundary conditions in the context of fluid flow and elasticity. This volume should be valuable for any researcher pursuing modern developments in the theory and applications of phase transitions and interface dynamics.
