摘要：

In this paper, a Stefan problem from theoretical glaciology with Dirichlet-Signorini boundary conditions is analyzed. The existence of a weak solution for the nonlinear evolutive model is shown by using an implicit time discretization, an enthalpy regularization procedure, and a Galerkin-type method. The main goal has been to adapt the previous techniques to the specific boundary conditions of the problem. (C) 2001 Academic Press.
