Semi-classical analysis of Schrödinger operators and compactness in the ∂-Neumann problem

Abstract: 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 and the relationship of this behavior with compactness in thē ∂-Neumann problem on Hartogs domains in C 2 .

“…It is noteworthy that whereas the underpinning of Witten's approach is a semi-classical analysis of Schrödinger operators without magnetic fields, Demailly's holomorphic Morse inequality is connected to Schrödinger operators with strong magnetic fields. (Interestingly, a related phenomenon also occurs in compactness in the ∂-Neumann problem for Hartogs domains in C 2 (see [FS02,CF05]): Whereas Catlin's property (P ) can be phrased in terms of semi-classical limits of non-magnetic Schrödinger operators, compactness of the ∂-Neumann operator reduces to Schrödinger operators with degenerated magnetic fields.) More recently, Berman established a local version of holomorphic Morse inequalities on compact complex manifolds [Ber04] and generalized Demailly's holomorphic Morse inequalities to complex manifolds with non-degenerated boundaries [Ber05].…”

“…These include global regularity [Kohn and Nirenberg 1965], the Fredholm theory of Toeplitz operators [Henkin and Iordan 1997], and the (non)existence of solution operators to ∂ with well-behaved solution kernels [Hefer and Lieb 2000]. There are also interesting connections to the theory of Schrödinger operators [Fu and Straube 2002;Christ and Fu 2005]. Catlin [1984] gave a sufficient condition, which he called property (P): near the boundary, there should exist plurisubharmonic functions bounded between 0 and 1 with arbitrarily large Hessians.…”

“…Property (P) was studied in detail (under the name B-regularity) by Sibony [1987]; see also [Sibony 1991]. On sufficiently regular domains, property (P) is equivalent to a quantitative version of Oka's lemma [Harrington 2007]. A version of property(P), called condition ( P), was introduced, and shown to still imply compactness, by McNeal [2002].…”
