Observations regarding compactness in the $\partial$ -Neumann problem

Mehmet Çelik, Emil J. Straube

We show that compactness of the $\partial$ -Neumann operator is independent of the metric, and we give a new proof of this independence for subellipticity. We define an a…

Compactness of the Complex Green Operator

Andrew S. Raich, Emil J. Straube

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 $b Ω$ implies compactness of the $\bar…

Complex tangential flows and compactness of the $\partial ˉ$ - Neumann operator

Samangi Munasinghe, Emil J. Straube

We provide geometric conditions on the set of boundary points of infinite type of a smooth bounded pseudoconvex domain in $C^{n}$ which imply that the $\partial ˉ$ -Neu…

Geometric conditions which imply compactness of the $\partial ˉ$ -Neumann operator

Emil J. Straube

For smooth bounded pseudoconvex domains in $ma t hbb C^{2}$ , we provide geometric conditions on (the points of infinite type in) the boundary which imply compactness of the $\bar{\p…

Semi-classical analysis of Schrodinger operators and compactness in the d-bar-Neumann problem

Siqi Fu, Emil J. Straube

We study the asymptotic behavior, in a ``semi-classical limit'', of the first eigenvalues (i.e. the groundstate energies) of a class of Schrödinger operators with magnetic fields a…

Compactness in the d-bar-Neumann problem

Siqi Fu, Emil J. Straube

This paper surveys the theory of compactness of the d-bar-Neumann problem. It also contains several results which improve upon what was previously known.
