Abstract | We consider the two-phase Stefan problem u t = ∆α(u) where α(u) = u + 1 for u < −1, α(u) = 0 for −1 ≤ u ≤ 1, and α(u) = u − 1 for u > 1. We show uniqueness of solutions which have signed measures as initial data, that is, we show that if the difference of two solutions u and v defined on Rn × (0, T ) vanishes in a weak sense as t → 0 then u = v a.e.
