A note on purely infinite extensions

Ping Wong Ng, Cangyuan Wang

We study a strong pure infiniteness property for extensions, and give a classification result for extensions which contains many (and possibly all) previous cases, under standard a…

A note on purely infinite corona algebras and extensions

Ping Wong Ng, Cangyuan Wang

Let $A$ be a separable nuclear C*-algebra, and $B$ be a nonunital separable simple $Z$ -stable C*-algebra. Continuing the work from Gabe-Lin-Ng, we cla…

A note on proper asymptotic uniqueness for semifinite factors

Ping Wong Ng, Cangyuan Wang

Let $A$ be a separable nuclear C*-algebra, and let $M$ be a semifinite von Neumann factor with separable predual. Let $ϕ, ψ: \mathcal{A} \rightarrow \mathcal{M}…

Extensions of C*-algebras

James Gabe, Huaxin Lin, Ping Wong Ng

Let $A$ be a separable amenable $C^{*}$ -algebra and $B$ a non-unital and $σ$ -unital simple $C^{*}$ -algebra with continuous scale ( $B$ need not be stable). We classify, up to unitary eq…

The corona algebra of stablized Jiang-Su algebra

Huaxin Lin, Ping Wong Ng

Let $Z$ be the Jiang-Su algebra and $K$ the C*-algebra of compact operators on an infinite dimensional separable Hilbert space. We prove that the corona algebra $M({\…
