三层膜问题的自由边界正则性

Free boundary regularity in the triple membrane problem

Ovidiu Savin, Hui Yu

摘要:

研究了三弹性薄膜问题中自由边界的正则性。我们证明了对应于连续膜之间重合区域的两个自由边界在正则交点附近是$C^{1,\log}$ -超曲面。我们还研究了两种类型的奇异相交。第一类奇点被$C^{1,α}$ -超曲面局部覆盖。第二类奇点是分层的,每一层都局部地被一个$C^1$ -流形覆盖。

英文摘要:

We investigate the regularity of the free boundaries in the 3 elastic membranes problem. We show that the two free boundaries corresponding to the coincidence regions between consecutive membranes are $C^{1,\log}$-hypersurfaces near a regular intersection point. We also study two types of singular intersections. The first type of singular points are locally covered by a $C^{1,α}$-hypersurface. The second type of singular points stratify and each stratum is locally covered by a $C^1$-manifold.
