度量算子域上的巴拿赫代数

Banach Algebras Associated to Metric Operator Fields

Maysam Maysami Sadr

摘要:

受非交换几何和量子物理的启发,引入了“度规算符场”的概念。粗略地说,度量算子场是一个向量场,其值在一个C* 代数丛的自张量积中,满足类似于普通度量(距离函数)的性质。证明了任何这样的对象都自然对应于一个Banach *-代数,我们称之为Lipschitz代数,一类概率度量,以及(在一定条件下)一个Dixdom意义下的C* 代数的(非平凡)连续域.证明了对于取值于von Neumann代数的度量算子域,其对应的Lipschitz代数是对偶巴拿赫空间,并且在一定条件下,它们不是顺从的巴拿赫代数.一些例子和建设被认为是。我们还简要地讨论了量子引力的一个可能的应用。

英文摘要:

Motivated by noncommutative geometry and quantum physics, the concept of `metric operator field' is introduced. Roughly speaking, a metric operator field is a vector field on a set with values in self tensor product of a bundle of C*-algebras, satisfying properties similar to an ordinary metric (distance function). It is proved that to any such object there naturally correspond a Banach *-algebra that we call Lipschitz algebra, a class of probabilistic metrics, and (under some conditions) a (nontrivial) continuous field of C*-algebras in the sense of Dixmier. It is proved that for metric operator fields with values in von Neumann algebras the associated Lipschitz algebras are dual Banach spaces, and under some conditions, they are not amenable Banach algebras. Some examples and constructions are considered. We also discuss very briefly a possible application to quantum gravity.
