Reduction to dimension two of local spectrum for $AH$ algebra with ideal property. (arXiv:1607.07578v2 [math.OA] UPDATED)
来源于:arXiv
A $C^{*}$-algebra $A$ has ideal property if any ideal $I$ of $A$ is generated
as an ideal by the projections inside the ideal. Suppose that the limit
$C^{*}$-algebra $A$ of inductive limit of direct sums of matrix algebras over
spaces with uniformly bounded dimension has ideal property. In this paper we
will prove that $A$ can be written as an inductive limit of certain very
special subhomogeneous algebras, namely, direct sum of dimension drop interval
algebras and matrix algebras over 2-dimensional spaces with torsion $H^{2}$
groups. This result unifies such reduction theorems for real rank zero $AH$
algebras in [EGS] and [DG] and for simple $AH$ algebras in [Li4]. The result
play essential role in the classification of $AH$ algebra with ideal property
(see [GJL]). 查看全文>>
