一类奇异拟线性方程的点态梯度估计

Pointwise gradient estimates for a class of singular quasilinear equation with measure data

Quoc-Hung Nguyen, Nguyen Cong Phuc

摘要:

在$\mathbb{R}^n$中的有界且可能是非光滑的区域$Ω$中,得到了具有测量数据$-\operatorname{div}(A(x,\nabla u))=μ$的拟线性椭圆型方程解的局部和整体逐点梯度估计.这里,$\operatorname{div}(A(x,\nabla u))$是在$p$ -拉普拉斯算子之后建模的。我们的结果扩展了以前已知的结果的奇异情况下,其中$\frac{3n-2}{2n-1}<p\leq 2-\frac{1}{n}$。

英文摘要:

Local and global pointwise gradient estimates are obtained for solutions to the quasilinear elliptic equation with measure data $-\operatorname{div}(A(x,\nabla u))=μ$ in a bounded and possibly nonsmooth domain $Ω$ in $\mathbb{R}^n$. Here $\operatorname{div}(A(x,\nabla u))$ is modeled after the $p$-Laplacian. Our results extend earlier known results to the singular case in which $\frac{3n-2}{2n-1}<p\leq 2-\frac{1}{n}$.
