复Green算子的Compactness

Compactness of the Complex Green Operator

Andrew S. Raich, Emil J. Straube

摘要:

设$Ω\subset\C^n$是有界光滑拟凸域.证明了复Green算子$G_{q}$在$bΩ$上的$(0,q)$ -形式上的紧性蕴涵了$Ω$上的$\bar{\partial}$ -Neumann算子$N_{q}$的紧性.证明了如果$1 \leq q \leq n-2$和$bΩ$满足$(P_q)$和$(P_{n-q-1})$,则$G_{q}$是紧算子($G_{n-1-q}$也是紧算子).我们的方法依赖于一个跳跃型公式来表示形式的边界上,我们证明了一个辅助的紧性结果之间的两个伪凸域的“环”。结合局部可凸域上$\bar{\partial}$ -Neumann问题中紧性的已知特征,我们的结果给出了这些区域上复Green算子紧性的相应特征.

英文摘要:

Let $Ω\subset\C^n$ be a bounded smooth pseudoconvex domain. We show that compactness of the complex Green operator $G_{q}$ on $(0,q)$-forms on $bΩ$ implies compactness of the $\bar{\partial}$-Neumann operator $N_{q}$ on $Ω$. We prove that if $1 \leq q \leq n-2$ and $bΩ$ satisfies $(P_q)$ and $(P_{n-q-1})$, then $G_{q}$ is a compact operator (and so is $G_{n-1-q}$). Our method relies on a jump type formula to represent forms on the boundary, and we prove an auxiliary compactness result for an `annulus' between two pseudoconvex domains. Our results, combined with the known characterization of compactness in the $\bar{\partial}$-Neumann problem on locally convexifiable domains, yield the corresponding characterization of compactness of the complex Green operator(s) on these domains.
