具有奇异低阶项的二阶椭圆型方程解的定量唯一性

Quantitative uniqueness of solutions to second order elliptic equations with singular lower order terms

Blair Davey, Jiuyi Zhu

摘要:

本文研究了具有奇异低阶项的二阶椭圆型方程解的定量唯一性。我们通过估计解的最大消失阶来量化强唯一连续性。也就是说,当$u$是$\triangle u + W \cdot \nabla u + V u = 0$在$\mathbb R^n$的某个开的连通子集中的非平凡解时,其中$n \geq 3$,我们用$V$和$W$在它们各自的Lebesgue空间中的范数来刻画解的消失阶。使用这些最大阶的消失估计,我们还建立了定量的唯一的连续在无穷远的解决方案,$\triangle u + W \cdot \nabla u + V u = 0$在$\mathbb R^n$的结果。在我们的工作中的主要工具是新版本的$L^p\to L^q$ Carleman估计范围的$p$ -和$q$ -值。

英文摘要:

In this article, we study the quantitative uniqueness of solutions to second order elliptic equations with singular lower order terms. We quantify the strong unique continuation property by estimating the maximal vanishing order of solutions. That is, when $u$ is a non-trivial solution to $\triangle u + W \cdot \nabla u + V u = 0$ in some open, connected subset of $\mathbb R^n$, where $n \geq 3$, we characterize the vanishing order of solutions in terms of the norms of $V$ and $W$ in their respective Lebesgue spaces. Using these maximal order of vanishing estimates, we also establish quantitative unique continuation at infinity results for solutions to $\triangle u + W \cdot \nabla u + V u = 0$ in $\mathbb R^n$. The main tools in our work are new versions of $L^p\to L^q$ Carleman estimates for a range of $p$- and $q$-values.
