单C* 代数的中间C*-子代数的扰动

Perturbations of intermediate C*-subalgebras for simple C*-algebras

Shoji Ino, Yasuo Watatani

摘要:

研究了单C* 代数包含的中间C*-子代数的一致扰动.如果一个有单位元的单C* 代数-代数有一个有限指标的单C *-子代数,则充分接近的单中间C*-子代数是酉等价的.这些C*-子代数不需要是核的。在相对交换子代数中可以选择酉。一个直接推论如下:如果相对交换子是平凡的,则中间C*-子代数的集合是有限集。

英文摘要:

We study uniform perturbations of intermediate C*-subalgebras of inclusions of simple C*-algebras. If a unital simple C*-algebra has a simple C*-subalgebra of finite index, then sufficiently close simple intermediate C*-subalgebras are unitarily equivalent. These C*-subalgebras need not to be nuclear. The unitary can be chosen in the relative commutant algebra. An imediate corollary is the following: If the relative commutant is trivial, then the set of intermediate C*-subagebras is a finite set.
