高阶抛物方程和薛定谔方程通过超平面的唯一延拓

Unique continuation through hyperplane for higher order parabolic and Schrödinger equations

Tianxiao Huang

摘要:

考虑$X=\{(t,x)\in\mathbb{R}^{1+n};~|t|<A,|x_n|<B\}$中的高阶抛物算子$\partial_t+(-Δ_x)^m$和高阶薛定谔算子$i^{-1}\partial_t+(-Δ_x)^m$,其中$m$和$n$是任意正整数。在一定的低阶和正则性假设下,我们证明了如果线性问题的解在$x_n>0$时消失,那么解在$X$中消失。如果是$n>1$,则这些结果是全局的,并且我们也证明了一些相关的局部结果.

英文摘要:

Consider the higher order parabolic operator $\partial_t+(-Δ_x)^m$ and the higher order Schrödinger operator $i^{-1}\partial_t+(-Δ_x)^m$ in $X=\{(t,x)\in\mathbb{R}^{1+n};~|t|<A,|x_n|<B\}$, where $m$ and $n$ are any positive integers. Under certain lower order and regularity assumptions, we prove that if solutions to the linear problems vanish when $x_n>0$, then the solutions vanish in $X$. Such results are global if $n>1$, and we also prove some relevant local results.
