A category is described to which the Cuntz semigroup belongs and as a functor into which it preserves inductive limits. 1. Recently, Toms in [26] used the refinement of the invariant K 0 introduced by Cuntz almost thirty years ago in [4] to show that certain C*-algebras are not isomorphic. Anticipating the possible use of this invariant to establish… (More)

We report on recent progress in the program to classify separable amenable C *-algebras. Our emphasis is on the newly apparent role of regularity properties such as finite decomposition rank, strict comparison of positive elements, and Z-stability, and on the importance of the Cuntz semigroup. We include a brief history of the program's successes since… (More)

It is shown that, for a C*-algebra of stable rank one (i.e., in which the invertible elements are dense), two well-known isomorphism invari-ants, the Cuntz semigroup and the Thomsen semigroup, contain the same information. More precisely, these two invariants, viewed appropriately, determine each other in a natural way. 1. In [4], Cuntz introduced an… (More)

Experimental allergic encephalomyelitis (EAE) was induced in female rats and a comparison of the effects of melengestrol acetate (MGA) and hydrocortisone acetate (HCA) was made. A dose response relation was observed. 2-4 mg MGA/kg/day delayed onset of the disease and 16 mg/kg/d ay for 19 days completely inhibited the disease. 20 mg HCA was comparable to… (More)

Mefenamic acid, given orally to rats at a single dose of 1200 mg/kg, produced renal papillary necrosis (RPN) in 63% of animals. The incidence was reduced to 27% by 16,16-dimethyl PGE2 (dmPGE2), given at an oral dose of 0.75 mg/kg t.i.d. RPN is likely to be caused by the renal prostaglandin depletion elicited by mefenamic acid, an inhibitor of prostaglandin… (More)

We show that in the generic case the smooth noncom-mutative tori associated to two n×n real skew-symmetric matrices are Morita equivalent if and only if the matrices are in the same orbit of the natural SO(n, n| Z) action.

A common generalization is given of what are often referred to as the Weyl–von Neumann theorems of Voiculescu, Kasparov, Kirchberg, and, more recently, Lin. (These in turn extend a result of Brown, Douglas, and Fillmore.) More precisely, an intrinsic characterization is obtained of those extensions of one separable C *-algebra by another—the first, i.e.,… (More)
