Abstract

For a planar domain Ω, we consider the Dirichlet spaces with respect to a base point

ζ \in Ω

and the corresponding kernel functions. It is not known how these kernel functions behave as we vary the base point. In this note, we prove that these kernel functions vary smoothly. As an application of the smoothness result, we prove a Ramadanov-type theorem for these kernel functions on

Ω \times Ω

. This extends the previously known convergence results of these kernel functions. In fact, we have made these observations in a more general setting, that is, for weighted kernel functions and their higher-order counterparts.

关于 Dirichlet 空间核函数的说明

对于平面域 Ω，我们考虑关于基点 ζ∈Ω 的 Dirichlet 空间和相应的核函数。我们还不知道这些核函数在我们改变基点时是如何表现的。在本说明中，我们将证明这些核函数的变化是平滑的。作为平滑性结果的应用，我们证明了这些核函数在 Ω×Ω 上的拉马丹诺夫型定理。这扩展了之前已知的这些核函数的收敛结果。事实上，我们是在更一般的情况下，即针对加权核函数及其高阶对应函数，得出这些结论的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
