General Information

The Interface Problems Workshop for the SAMSI program on Random Media will be held on Thursday - Friday, November 15 - 16, 2007, at the Radisson Hotel RTP in Research Triangle Park, NC.

This workshop will concentrate on modeling, theory, numerical methods, statistics, and applications of interface problems including free boundary, moving interface problems and problems defined on irregular domains.

In many science and engineering problems, multiphase systems that involve moving interfaces and free boundaries are challenging from the perspective of both mathematical analysis and numerical simulations. One of the primary difficulties involves the coupling between evolution and geometry of the interface with the global dynamics of the bulk material. This coupling is often nonlinear and non-local. Singularities, such as discontinuity of material properties and physical quantities across the interface, and topological changes, such as merging and pinch-off, occur during the evolution. Further complications, such as surface diffusion, random media, and multiple scales, add to the challenges associated with these problems.

Recently there has been significant progress in both theory and numerical methods for moving interface problem. In this workshop, experts from a variety of backgrounds will address different aspects in modeling, theory, numerical methods and applications.
