M. Dadarlat et G. Gong, A CLASSIFICATION RESULT FOR APPROXIMATELY HOMOGENEOUS C-ASTERISK-ALGEBRAS OF REAL RANK ZERO, Geometric and functional analysis, 7(4), 1997, pp. 646-711
We prove that the total K-theory group (K) under bar(-) = +(infinity)(
n=0) K(-;Z/n) equiped with a natural order structure and acted upon b
y the Bockstein operations is a complete invariant for a class of appr
oximately subhomogeneous C-algebras of real rank zero which include t
he inductive limits of systems of the form P1Mn(1)(C(X-1))P-1-->P2Mn(2
)(C(X-2))P-2-->... where Pi are selfadjoint projections in M-n(i)(C(X-
i)) and X-i are finite (possibly disconnected) CW complexes whose dime
nsions satisfy a certain growth condition. The problem of finding suit
able invariants for the study of C-algebras of this type was proposed
by Effros. Our result represents a substantial generalization of the
classification theorem of approximately finite dimensional (AF) C-alg
ebras, due to Elliott.
