Purely Infinite Corona Algebras and Extensions

چکیده
We classify all essential extensions of the form 0 → B → D → C(X) → 0 where B is a nonunital simple separable finite real rank zero Z-stable C*algebra with continuous scale, and where X is a finite CW complex. In fact, we prove that there is a group isomorphism Ext(C(X),B) → KK(C(X),M(B)/B).

Purely Infinite Corona Algebras of Simple C∗-algebras
In this paper we study the problem of when the corona algebra of a non-unital C∗-algebra is purely infinite. A complete answer is obtained for stabilisations of simple and unital algebras that have enough comparison of positive elements. Our result relates the pure infiniteness condition (from its strongest to weakest forms) to the geometry of the tracial simplex of the algebra, and to the beha...
متن کاملAbsorbing Representations with Respect to Closed Operator Convex Cones
We initiate the study of absorbing representations of C-algebras with respect to closed operator convex cones. We completely determine when such absorbing representations exist, which leads to the question of characterising when a representation is absorbing, as in the classical Weyl–von Neumann type theorem of Voiculescu. In the classical case, this was proven by Elliott and Kucerovsky who pro...
متن کاملA Classification Theorem for Direct Limits of Extensions of Circle Algebras by Purely Infinite C*-algebras
We give a classification theorem for a class of C*-algebras which are direct limits of finite direct sums of E0-algebras. The invariant consists of the following: (1) the set of Murray-von Neumann equivalence classes of projections; (2) the set of homotopy classes of hyponormal partial isometries; (3) a map d; and (4) total K-theory.
متن کاملA Rohlin Type Theorem for Automorphisms of Certain Purely Infinite C∗-Algebras
We show a noncommutative Rohlin type theorem for automorphisms of a certain class of purely infinite simple C∗-algebras. This class consists of the purely infinite unital simple C∗-algebras which are in the bootstrap category N and have trivial K1-groups.
متن کاملSemiprojectivity for Certain Purely Infinite C-algebras
It is proved that classifiable simple separable nuclear purely infinite C∗algebras having finitely generated K-theory and torsion-free K1 are semiprojective. This is accomplished by exhibiting these algebras as C∗-algebras of infinite directed graphs.
