Global regularity of the \(\overline{\partial}\)-Neumann problem on circular domains. (English) Zbl 0662.32016

We show that if \(D\subseteq {\mathbb{C}}^ n\), \(n\geq 2\), is a smooth bounded pseudoconvex circular domain with \(\sum^{n}_{i=1}z_ i\frac{\partial r}{\partial z_ i}\neq 0\) near the boundary, where r(z) is the defining function for D, then global regularity of the \({\bar \partial}\)-Neumann problem holds on D. More precisely, if given \(f\in W^ k_{p,q}(D)\), let \(u\in L^ 2_{q,p}(D)\) be the solution to the \({\bar \partial}\)- Neumann problem, \[ Q(u,v)=({\bar \partial}u,{\bar \partial}v)+({\vec \partial}u,{\vec \partial}v)=(f,v), \] for all \(v\in \tilde {\mathcal D}_{p,q}(D)\), then \(u\in W^ k_{p,q}(D)\) and \(\| u\|_ k\leq C_ k\| f\|_ k\), where \(W^ k_{p,q}(D)\) is the Sobolev space of order k on D and \(\tilde {\mathcal D}_{p,q}(D)\) is the completion of smooth (p,q)-forms with Neumann boundary conditions under Q. We also prove that same conclusions hold on any smooth bounded Reinhardt pseudoconvex domain. As an application we show that same results hold on Sibony’s domain that is a smooth bounded weakly pseudoconvex domain in \({\mathbb{C}}^ 3\), but fails to have sup-norm estimate for the \({\bar \partial}\)-equation.
