摘要
本文旨在介绍和研究几乎有限p-收敛和弱(weak\(^*\) almost p-收敛算子(\(1 \le p <\infty \))这类算子。我们得到了具有强有限p-Schur性质的巴拿赫网格的一些新特征;也就是说,在这些空间上,每个几乎有限的弱p-协集都是相对紧凑的,并且具有p阶的弱DP(^*\)性质。研究了这些具有弱 DP\(^*\) 属性的 p 阶算子的行为(重点是具有强有限 p-Schur 属性的巴拿赫网格)。此外,还引入了具有正有限 p-Schur 性质的巴拿赫网格,并讨论了该性质等同于其他一些已知性质的巴拿赫网格。此外,还考虑了几乎有限 p-congent 和 weak\(^*\) almost p-congent 算子的支配性质。作为应用,我们利用几乎有限 p-convergent 算子建立了一些必要条件和充分条件,在这些条件下,一些算子空间具有强有限 p-Schur 性质。
On almost limited p-convergent operators on Banach lattices
The purpose of this article is to introduce and study the class of almost limited p-convergent and weak\(^*\) almost p-convergent operators (\(1 \le p <\infty \)). Some new characterizations of Banach lattices with the strong limited p-Schur property; that is, spaces on which every almost limited weakly p-compact set is relatively compact and the weak DP\(^*\) property of order p are obtained. The behavior of the class of these operators with the weak DP\(^*\) property of order p (with focus on Banach lattices with the strong limited p-Schur property) is investigated. Moreover, Banach lattices with the positive limited p-Schur property are introduced and Banach lattices in which this property is equivalent to some other known properties are discussed. In addition, the domination properties of almost limited p-convergent and weak\(^*\) almost p-convergent operators are considered. As an application, using almost limited p-convergent operators we establish some necessary and sufficient conditions under which some operator spaces have the strong limited p-Schur property.
期刊介绍:
The purpose of Positivity is to provide an outlet for high quality original research in all areas of analysis and its applications to other disciplines having a clear and substantive link to the general theme of positivity. Specifically, articles that illustrate applications of positivity to other disciplines - including but not limited to - economics, engineering, life sciences, physics and statistical decision theory are welcome.
The scope of Positivity is to publish original papers in all areas of mathematics and its applications that are influenced by positivity concepts.
