(International conference on free and moving boundary problems)
DUDLEY WILSON · 1988
The conference consisted of audiovisual presentations and discussions eight hours per day for three full days spread over four and one half days. A wide range of free and moving boundary problems was presented. All the talks except those given by the traveler and by Krystyna Twardowska were in Spanish. The traveler attended all presentations. However, his Spanish is limited and it was totally inadequate for the rapid rate at which most of these presentations were delivered. He could, of course, follow the gist of presentations accompanied by adequate visual material. In particular, the presentations by Sr. Bouillet, on a variational inequality governing the distribution of energy in mushy regions, and by Sr. Vicente, on metallurgical aspects of alloy solidification, were understood and appreciated. The traveler gave two talks. The first was on an implicit finite difference discretization of the enthalpy method, and the second was on the application of this scheme to a multidimensional phase change problem involving a significant change in density on freezing.
