考虑了具有Dirichlet或非线性Neumann边界条件的奇异抛物型方程（u温度，γ（u）φ ph）.在一些定性的假设下的数据表明，糊状区描述的两个Lipschitz连续函数和。当，因此糊状区域不能自发出现，并且u满足非简并性质：
The singular parabolic equation with either Dirichlet or nonlinear Neumann boundary conditions is considered (u temperature, γ(u) enthalph). Under some qualitative assumptions upon the data it is shown that the mushy region is described by two Lipschitz-continuous functions and . When , hence mushy regions cannot appear spontaneously and u satisfies the non-degeneracy property: .
