Geometric conditions which imply compactness of the ∂ ¯-Neumann operator
[Conditions géométriques qui entraînent la compacité de l’opérateur ∂ ¯-Neumann]
Annales de l'Institut Fourier, Tome 54 (2004) no. 3, pp. 699-710.

On donne, pour les domaines lisses bornés pseudoconvexes de ℂ 2 , des conditions géométriques concernant le bord qui entraînent la compacité de l’opérateur ∂ ¯-Neumann. Il est remarquable que la preuve de la compacité ne procède pas par verification des conditions suffisantes bien connues de type théorie du potentiel.

For smooth bounded pseudoconvex domains in ℂ 2 , we provide geometric conditions on the boundary which imply compactness of the ∂ ¯-Neumann operator. It is noteworthy that the proof of compactness does not proceed via verifying the known potential theoretic sufficient conditions.
