Yuzhe Zhu

AI总结:

该研究探讨二维椭圆方程解的定量小性传播问题,证明了带Hölder连续系数的散度型方程与带可测系数的非散度型方程的解的梯度均可由正δ维Hausdorff容度的小集合定量估计。

摘要:

我们研究了二维椭圆方程的解从具有正δ维Hausdorff容度的集合出发的定量小性传播,其中δ>0。具体而言,带Hölder连续系数的散度型方程解的梯度,以及带可测系数的非散度型方程解的梯度,都可由这些小集合进行定量估计。

英文摘要:

We explore quantitative propagation of smallness for solutions of two-dimensional elliptic equations from sets of positive $δ$-dimensional Hausdorff content for any $δ>0$. In particular, the gradients of solutions to divergence form equations with Hölder continuous coefficients, as well as those of nondivergence form equations with measurable coefficients, can be quantitatively estimated from the small sets.
