Simplicity of the Bergman, Szego and Poisson kernel functions

The Bergman Kernel Function

In this note, we point out that a large family of n × n matrix valued kernel functions defined on the unit disc D ⊆ C, which were constructed recently in [9], behave like the familiar Bergman kernel function on D in several different ways. We show that a number of questions involving the multiplication operator on the corresponding Hilbert space of holomorphic functions on D can be answered usi...

The Fekete-Szego Coefficient Functional for Transforms of Analytic Functions

On the Asymptotic Expansion of Bergman Kernel

We study the asymptotic of the Bergman kernel of the spin Dirac operator on high tensor powers of a line bundle.

The Stability of the Bergman Kernel and the Geometry of the Bergman Metric

If D is a bounded open subset of C", the set H = {ƒ: D —> C| ƒ is holomorphic and SD\f\ 2 < +°°} is a separable infinite-dimensional Hubert space relative to the inner product <ƒ, g) = fDfg. The completeness of H can be seen from Cauchy integral estimates. Similar estimates show that for any p E D the functional ƒ H* ƒ(/?),ƒ£ H, is continuous. Thus there is a unique element KD(z, p) E f/ (as a ...

Subharmonicity Properties of the Bergman Kernel and Some Other Functions Associated to Pseudoconvex Domains

Let D be a pseudoconvex domain in Ckt × C n z and let φ be a plurisubharmonic function in D. For each t we consider the ndimensional slice of D, Dt = {z; (t, z) ∈ D}, let φ be the restriction of φ to Dt and denote by Kt(z, ζ) the Bergman kernel of Dt with the weight function φ. Generalizing a recent result of Maitani and Yamaguchi (corresponding to n = 1 and φ = 0) we prove that logKt(z, z) is ...
