Interfaces are geometrical objects modelling free or moving boundaries
and arise in a wide range of phase change problems in physical and
biological sciences, particularly in material technology and in dynamics
of patterns. Especially in the end of last century, the study of
evolving interfaces in a number of applied fields becomes increasingly
important, so that the possibility of describing their dynamics through
suitable mathematical models became one of the most challenging and
interdisciplinary problems in applied mathematics. The 2000 Madeira
school reported on mathematical advances in some theoretical, modelling
and numerical issues concerned with dynamics of interfaces and free
boundaries. Specifically, the five courses dealt with an assessment of
recent results on the optimal transportation problem, the numerical
approximation of moving fronts evolving by mean curvature, the dynamics
of patterns and interfaces in some reaction-diffusion systems with
chemical-biological applications, evolutionary free boundary problems of
parabolic type or for Navier-Stokes equations, and a variational
approach to evolution problems for the Ginzburg-Landau functional.
