AI 中文摘要
本文研究具有有限Radon测度和退化矩阵值权重的拟线性椭圆Dirichlet问题的解的存在性和局部梯度正则性。在$\mathbb M$满足小log-BMO条件的情况下,我们首先证明SOLA(通过逼近极限获得的解)的存在性,然后建立关于$|\mathbb{M}|^{\frac{1}{p-1}}\mathbb{M} Du$的局部Calderón-Zygmund估计,该估计以分数极大函数$\mathcal{M}_1(\mu)^{\frac{1}{p-1}}$表示。
英文摘要
This paper is concerned with the existence and local gradient regularity of solutions to a quasilinear elliptic Dirichlet problem with finite Radon measure and a degenerate matrix-valued weight. Under a small log-BMO condition on $\mathbb M$, we first prove the existence of a SOLA (solution obtained by a limit of approximations) and then establish a local Calderón-Zygmund estimate for $|\mathbb{M}|^{\frac{1}{p-1}}\mathbb{M} Du$ in terms of the fractional maximal function $\mathcal{M}_1(μ)^{\frac{1}{p-1}}$.
