The Stefan problem and applications El problema de Stefan y aplicaciones

Abstract

In this paper, we analyze the two-phase Stefan problem allowing the free boundary irregularities, which requires implicit treatment of the interface through weak formulations of the enthalpy to construct cost functional J (u, n(u), v(u)) subject to external control u in a limited domain (2 c R^N (N > 2), that has soft edge U and to for (1 < T < r> fixed, Q = Q x [O,T], L := an x  [ O, T].
