奇异$p$ -Laplacian算子Stefan问题弱解的局部连续性

Local continuity of weak solutions to the Stefan problem involving the singular $p$-Laplacian

Naian Liao

摘要:

我们建立了描述材料相变的双奇异抛物型方程的局部有界弱解(温度)的局部连续性:\[ \partial_t β(u)-Δ_p u\ni 0\quad\text{ for }\tfrac{2N}{N+1}<p<2, \]其中$β$是一个在零处有跳的极大单调图,$Δ_p$是$p$ -Laplacian。此外,还量化了一个对数型连续模,并证明它是最优的。

英文摘要:

We establish the local continuity of locally bounded weak solutions (temperatures) to the doubly singular parabolic equation modeling the phase transition of a material: \[ \partial_t β(u)-Δ_p u\ni 0\quad\text{ for }\tfrac{2N}{N+1}<p<2, \] where $β$ is a maximal monotone graph with a jump at zero and $Δ_p$ is the $p$-Laplacian. Moreover, a logarithmic type modulus of continuity is quantified, which has been conjectured to be optimal.
