Dini域上完全非线性方程的边界正则性

Borderline regularity for fully nonlinear equations in Dini domains

Karthik Adimurthi, Agnid Banerjee

摘要:

本文证明了完全非线性椭圆型方程黏性解在$C^{1,\dini}$ -区域边界上的边界梯度连续性。我们的主要结果定理3.1是由Ma-Wang证明的边界梯度估计在Daskalopoulos-Kuusi-Mingione建立的边界内梯度正则性估计之后的锐化。然而,我们提到,不同的方法在内部的情况下,这取决于$W^{1,q}$估计,我们的证明是稍微几何和紧凑性参数的基础上启发的技术在基本工程的卡法雷利。

英文摘要:

In this paper, we prove borderline gradient continuity of viscosity solutions to Fully nonlinear elliptic equations at the boundary of a $C^{1,\dini}$-domain. Our main result Theorem 3.1 is a sharpening of the boundary gradient estimate proved by Ma-Wang following the borderline interior gradient regularity estimates established Daskalopoulos-Kuusi-Mingione. We however mention that, differently from the approach in the interior case which depends on $W^{1,q}$ estimates, our proof is slightly more geometric and is based on compactness arguments inspired by the techniques in the fundamental works of Caffarelli.
