Abstract

Abstract In this paper, we provide a new norm(α-Berezin norm) on the space of all bounded linear operators defined on a reproducing kernel Hilbert space, which generalizes the Berezin radius and the Berezin norm. We study the basic properties of the α-Berezin norm and develop various inequalities involving the α-Berezin norm. By using the inequalities we obtain various bounds for the Berezin radius of bounded linear operators, which improve on the earlier bounds. Further, we obtain a Berezin radius inequality for the sum of the product of operators, from which we derive new Berezin radius bounds.

关于重核Hilbert空间算子和Berezin-Radius不等式空间上的一个新范数

摘要本文给出了在再现核Hilbert空间上定义的所有有界线性算子空间上的一个新范数(α-Berezin范数)，它推广了Berezin半径和Berezin范数。研究了α-Berezin范数的基本性质，给出了涉及α-Berezin范数的各种不等式。利用这些不等式，我们得到了有界线性算子的Berezin半径的各种边界，改进了先前的边界。进一步，我们得到了算子积和的Berezin半径不等式，并由此导出了新的Berezin半径界。

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.
