摘要

让 \(\mu \) 是[0, 1]上的一个正有限伯尔量。研究了作用于全形函数的加权空间时的 Cesàro 型算子 \(C_{\mu }\) 。在单位圆盘上有界全形函数的情况下,我们证明了\(C_\mu \)是连续的,当且仅当它是紧凑的。对于由一般权值定义的全形函数的加权巴拿赫空间,我们给出了连续性和紧凑性的充分必要条件。对于标准权重,我们描述了经典增长巴拿赫全形函数空间的连续性和紧凑性。我们还研究了圆盘上全纯函数空间、圆盘上有界全纯函数空间以及经典增长巴拿赫全纯函数空间上的点谱和\(C_\mu \)谱。所有特征都是通过矩序列 \((\mu _n)_{n\in {\mathbb {N}}_0}\) 给出的。还考虑了作用于弗雷谢特和(LB)科伦布卢姆类型空间的 \(C_\mu \) 的连续性、紧凑性和谱。

Cesàro operators associated with Borel measures acting on weighted spaces of holomorphic functions with sup-norms

Let \(\mu \) be a positive finite Borel measure on [0, 1). Cesàro-type operators \(C_{\mu }\) when acting on weighted spaces of holomorphic functions are investigated. In the case of bounded holomorphic functions on the unit disc we prove that \(C_\mu \) is continuous if and only if it is compact. In the case of weighted Banach spaces of holomorphic function defined by general weights, we give sufficient and necessary conditions for the continuity and compactness. For standard weights, we characterize the continuity and compactness on classical growth Banach spaces of holomorphic functions. We also study the point spectrum and the spectrum of \(C_\mu \) on the space of holomorphic functions on the disc, on the space of bounded holomorphic functions on the disc, and on the classical growth Banach spaces of holomorphic functions. All characterizations are given in terms of the sequence of moments \((\mu _n)_{n\in {\mathbb {N}}_0}\). The continuity, compactness and spectrum of \(C_\mu \) acting on Fréchet and (LB) Korenblum type spaces are also considered .

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.
