与具有一维自相关算子的指数核

An exponential kernel associated with operators that have one-dimensional self-commutators

Kevin F. Clancey

摘要:

指数核\[E{g}(λ,w) = \exp -\frac{1}π\int_{\mathbb{C} } \frac{g(u)}{\overline{u-w} (u-λ) } da(u ),\](其中复支撑有界可测函数$g$满足$0 \leq g\leq 1,$并对所有复$λ, w,$适当定义)在具有一维自映射的希尔伯特空间算子理论和求积域理论中起着重要作用。本文研究了$E_{g}$的连续性和整表示性质,并进一步将其应用于一维自换位子算子。

英文摘要:

The exponential kernel \[E{g}(λ,w) = \exp -\frac{1}π\int_{\mathbb{C} } \frac{g(u)}{\overline{u-w} (u-λ) } da(u ),\] where the compactly supported bounded measurable function $g$ satisfies $0 \leq g\leq 1,$ and suitably defined for all complex $λ, w,$ plays a role in the theory of Hilbert space operators with one-dimensional self-commutators and in the theory of quadrature domains. This article studies continuity and integral representation properties of $E_{g}$ with further applications of this exponential kernel to operators with one-dimensional self-commutator.
