Homogenization of one-phase Stefan-type problems in periodic and random media
Inwon Kim, Antoine Mellet · Transactions of the American Mathematical Society · 2010
We investigate the homogenization of Stefan-type problems with oscillating diffusion coefficients. Both cases of periodic and random (stationary ergodic) mediums are considered. The proof relies on the coincidence of viscosity solutions and weak solutions (which are the time derivatives of the solutions of an obstacle problem) for the Stefan problem. This coincidence result is of independent interest.
