Abstract

In recent years, the study of bounded linear operators in several variables has received great interest from many authors, including the second author’s previous contributions. In our present work, we define a new class of multivariable operator theory, which we have called M-hyponormal tuple. We present some algebraic and spectral properties associated with them.

多变量算子理论中的 M-hyponormality

近年来，多变量有界线性算子的研究受到了许多学者的极大关注，包括第二作者之前的贡献。在我们目前的工作中，我们定义了一类新的多变量算子理论，我们称之为 M-hyponormal tuple。我们提出了与之相关的一些代数和谱性质。

期刊介绍： The aim of this journal is to provide a multi-disciplinary forum of discussion in mathematics and its applications in which the essentiality of inequalities is highlighted. This Journal accepts high quality articles containing original research results and survey articles of exceptional merit. Subject matters should be strongly related to inequalities, such as, but not restricted to, the following: inequalities in analysis, inequalities in approximation theory, inequalities in combinatorics, inequalities in economics, inequalities in geometry, inequalities in mechanics, inequalities in optimization, inequalities in stochastic analysis and applications.
