"NettetWe show how the Stefan free boundary problem arises in this fast reaction limit. Depending on the unscaled reaction-diffusion system, two cases are recovered, with or without latent heat. Because of the strong nonlinearity, compactness is needed to justify the asymptotic behavior. " - Lecture notes on the stefan problem
