AI总结:

该研究通过双倍自由边界极小锥构造了球面上的新极小曲面,并展示了毛细功能在单相自由边界与极小曲面之间的联系。

摘要:

对于每一个p,q≥1,我们通过双倍自由边界极小锥在R^{p+q+3}中的双链,构造了S^p×S^q×S^1在S^{p+q+2}中的极小嵌入。这解决了Hsiang-Lawson和Hsiang-Hsiang提出的问题。等变性将极小曲面方程简化为一个微分方程,我们证明了对于每一个接触角都存在毛细极小锥。我们通过一个具有无限初始斜率的奇异射击问题,获得自由边界解作为毛细面的极限。当接触角退化到0时,毛细锥的缩放收敛到一个相变伯努利问题的齐次解,进一步通过毛细功能展示了单相自由边界与极小曲面之间的联系。

英文摘要:

For every $p,q\geq 1$, we construct minimal embeddings of $\mathbb{S}^p \times \mathbb{S}^q \times \mathbb{S}^1$ in $\mathbb{S}^{p + q + 2}$ by doubling the links of free-boundary minimal cones in $\mathbb{R}^{p+q+3}$ with bi-orthogonal symmetry. This solves problems posed by Hsiang-Lawson and Hsiang-Hsiang. The equivariance reduces the minimal surface equation to an ODE, and we prove the existence of capillary minimal cones for every contact angle. We obtain free-boundary solutions as limits of capillary surfaces via a singular shooting problem with infinite initial slope. As the contact angle degenerates to $0$, rescalings of the capillary cones converge to a homogeneous solution of the one-phase Bernoulli problem, further illustrating the connection between one-phase free boundaries and minimal surfaces through the capillary functional.
