C*-丛动力系统

C*-bundle dynamical systems

Rachel A. D. Martins

摘要:

引入了C*-丛动力系统,研究了它们在C*-子代数和Fell丛理论中的作用.一个C*-丛动力系统包含了一个C*-丛的“空间自同构”的单参数群的作用以及关于基流形的空间自同构的协方差的概念,并定义了一类Arveson的$A$ -动力系统的例子。一个嵌入不变量的非交换C*-子代数(相当于一个广群2-上圈的建设)出现,并表示类似于一个分拆函数对潜在的代数公式的量子引力。

英文摘要:

C*-bundle dynamical systems are introduced and their rôle within the theory of C*-subalgebras and Fell bundles is investigated. A C*-bundle dynamical system involves an action of a 1-parameter group of "spatial automorphisms" of the C*-bundle together with a notion of covariance with respect to the diffeomorphisms of the base manifold, and turns out to define a class of examples of Arveson's $A$-dynamical systems. An embedding invariant for non-commutative C*-subalgebras (equivalent to a groupoid 2-cocycle by construction) emerges and has presentation analogous to a partition function towards a potential algebraic formulation of quantum gravity.
