Segal代数的量子调和分析方法

A Quantum Harmonic Analysis Approach to Segal Algebras

Eirik Berge, Stine Marie Berge, Robert Fulsche

摘要:

本文研究了空间$L^1(\mathbb{R}^{2n})\oplus \mathcal{T}^1$上的交换巴拿赫代数结构,其中$\mathcal{T}^1$表示$L^2(\mathbb{R}^{n})$上的迹族算子.这个空间的乘积由量子调和分析中的卷积给出。为了这个目标,我们研究这个空间的封闭理想,特别是它的Gelfand理论。我们还开发了量子Segal代数的概念作为Segal代数的模拟。我们证明了Segal代数的许多性质可以转移到量子Segal代数上。然而,应该注意的是,与Segal代数相反,量子Segal代数不是环境空间的理想。我们还给出了不同的结构,产生量子西格尔代数的例子。

英文摘要:

In this article, we study a commutative Banach algebra structure on the space $L^1(\mathbb{R}^{2n})\oplus \mathcal{T}^1$, where the $\mathcal{T}^1$ denotes the trace class operators on $L^2(\mathbb{R}^{n})$. The product of this space is given by the convolutions in quantum harmonic analysis. Towards this goal, we study the closed ideals of this space, and in particular its Gelfand theory. We additionally develop the concept of quantum Segal algebras as an analogue of Segal algebras. We prove that many of the properties of Segal algebras have transfers to quantum Segal algebras. However, it should be noted that in contrast to Segal algebras, quantum Segal algebras are not ideals of the ambient space. We also give examples of different constructions that yield quantum Segal algebras.
