弱正则区域上的预定中曲率方程

The prescribed mean curvature equation in weakly regular domains

Gian Paolo Leonardi, Giorgio Saracco

摘要:

我们表明,存在性和唯一性的表征,以规定的中曲率方程,最初证明了Giusti在光滑的情况下,解决方案的垂直平移,持有真正的域满足非常温和的正则性假设。我们的结果特别适用于非参数解决方案的毛细问题,完全润湿流体在零重力。在必要的工具中使用的证明,我们提到了一个\textit{generalized Gauss-Green theorem}的基础上建设的弱正常跟踪的向量场有界发散,在精神上的经典结果由于Anzellotti,和一个\textit{weak Young's law}的$(Λ,r_{0})$ -极小的周长。

英文摘要:

We show that the characterization of existence and uniqueness up to vertical translations of solutions to the prescribed mean curvature equation, originally proved by Giusti in the smooth case, holds true for domains satisfying very mild regularity assumptions. Our results apply in particular to the non-parametric solutions of the capillary problem for perfectly wetting fluids in zero gravity. Among the essential tools used in the proofs, we mention a \textit{generalized Gauss-Green theorem} based on the construction of the weak normal trace of a vector field with bounded divergence, in the spirit of classical results due to Anzellotti, and a \textit{weak Young's law} for $(Λ,r_{0})$-minimizers of the perimeter.
