The corresponding mathematical model consists of the Stefan problem with radial symmetry. We obtain asymptotic expansions for the radius of the melting ball which turn out to be of a different nature according to the cases N greater than or equal to 3 and N = 2, N being the space dimension. The methods employed combine matched asymptotic expansion techniques, a priori estimates, and topological results.engjournal articlehttp://epubs.siam.org/simax/resource/1/sjmaah/v28/i1/p1_s1?isAuthorized=nohttp://epubs.siam.orgrestricted access517.956.4536.2Stefan problemasymptotic behaviormatched asymptotic expansionsa priori estimatessemilinear heat-equationsblow-upparabolic equationsEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
