三维Muskat问题的最终正则化:有限时间Lipschitz蕴含全局存在性
Eventual regularization for the 3D Muskat problem: Lipschitz for finite time implies global existence
摘要:
我们证明了对于任何固定的Lipschitz常数$L$,存在一个时间$L$只依赖于$L$,使得如果$f:[0,T^*]\times \mathbb{R}^{2}\to [0,1]$是具有$||\nabla_x f||_{L^\infty}\leq L$的稳定Muskat问题的经典解,则$f$唯一地扩展到一个定义为所有时间的经典解.我们的证明是简短、定量和明确的。
英文摘要:
We show that for any fixed Lipschitz constant $L$, there is a time $T^*<\infty$ depending only on $L$ such that if $f:[0,T^*]\times \mathbb{R}^{2}\to [0,1]$ is a classical solution of the stable Muskat problem with $||\nabla_x f||_{L^\infty}\leq L$, then $f$ extends uniquely to a classical solution defined for all time. Our proof is short, quantitative, and explicit.
