C* 代数丛的扩张

Extensions of Bundles of C*-algebras

Jeremy Steeger, Benjamin H. Feintzeig

摘要:

C* 代数的丛可以用来表示其代数结构依赖于参数值的物理理论的极限。主要的例子是量子理论中物理量的C* 代数的$\hbar\to 0$极限,在严格变形量子化的框架中表示。在本文中,我们理解这样的限制程序的C* 代数的一个丛的扩展到某个参数的极限值。我们证明存在性和唯一性结果,这样的扩展。此外,我们证明了这样的扩展是函的纤维C* 代数上的C*-产品,动力学自同构,和李括号(在$\hbar\to 0$的情况下)。

英文摘要:

Bundles of C*-algebras can be used to represent limits of physical theories whose algebraic structure depends on the value of a parameter. The primary example is the $\hbar\to 0$ limit of the C*-algebras of physical quantities in quantum theories, represented in the framework of strict deformation quantization. In this paper, we understand such limiting procedures in terms of the extension of a bundle of C*-algebras to some limiting value of a parameter. We prove existence and uniqueness results for such extensions. Moreover, we show that such extensions are functorial for the C*-product, dynamical automorphisms, and the Lie bracket (in the $\hbar\to 0$ case) on the fiber C*-algebras.
