两阶段自由边界问题(几乎-)极小解的分支点

Branch Points for (Almost-)Minimizers of Two-Phase Free Boundary Problems

Guy David, Max Engelstein, Mariana Smit Vega Garcia, Tatiana Toro

摘要:

研究了两相自由边界问题分支点的存在性和结构。更准确地说,我们构造了一个家庭的极小化的Alt-Caffarelli-弗里德曼型功能的自由边界包含分支点的严格内部的域。我们还给出了一个例子,表明分支点的自由边界几乎极小的相同功能可以有很小的结构。这最后一个例子站在对比最近的结果德Philippis-Spollichkov结构的分支点在自由边界的固定解决方案。

英文摘要:

We study the existence and structure of branch points in two-phase free boundary problems. More precisely, we construct a family of minimizers to an Alt- Caffarelli-Friedman type functional whose free boundaries contain branch points in the strict interior of the domain. We also give an example showing that branch points in the free boundary of almost-minimizers of the same functional can have very little structure. This last example stands in contrast with recent results of De Philippis- Spolaor-Velichkov on the structure of branch points in the free boundary of stationary solutions.
