关于CCR C* 代数的高实稳定秩

On higher real and stable ranks for CCR C*-algebras

Lawrence G. Brown

摘要:

计算了只有有限维不可约表示和拓扑维数有限的CCR代数的实秩和稳定秩。我们证明了在四种情况下,A的任一秩都由理想I的秩和商A/I决定:当A是CCR时,当I只有有限维不可约表示时,当I是可分的,具有广义连续迹和有限拓扑维数,且I的所有不可约表示都是无限维时;或者当I是可分的,稳定的,有一个由投影组成的近似恒等式,并且具有冠因子分解性质。本文还给出了M(A)的高秩反例,A的次齐次,以及P. Green关于广义连续迹代数的一个定理。

英文摘要:

We calculate the real rank and stable rank of CCR algebras which either have only finite dimensional irreducible representations or have finite topological dimension. We show that either rank of A is determined in a good way by the ranks of an ideal I and the quotient A/I in four cases: When A is CCR; when I has only finite dimensional irreducible representations; when I is separable, of generalized continuous trace and finite topological dimension, and all irreducible representations of I are infinite dimensional; or when I is separable, stable, has an approximate identity consisting of projections, and has the corona factorization property. We also present a counterexample on higher ranks of M(A), A subhomogeneous, and a theorem of P. Green on generalized continuous trace algebras.
