The vanishing latent heat limit of a stochastic Stefan problem : An error estimate
Ioana Ciotir, Perla El Kettani, Dan Goreac +1
The purpose of this paper is to extend an article by Hilhorst, Mimura and Sch{ä}tzle [18] about the limit as the latent heat coefficient tends to zero of a two-phase Stefan problem…
