Extensions ofC*-Algebras by a Small Ideal
Autor: Huaxin Lin, Ping Wong Ng
Publikováno v: International Mathematics Research Notices.
We classify all essential extensions of the form $$ \begin{align*} &0 \rightarrow {\mathcal{W}} \rightarrow {D} \rightarrow A \rightarrow 0,\end{align*}$$where ${\mathcal {W}}$ is the unique separable simple C*-algebra with a unique tracial state, wh

Closed Convex Hulls of Unitary Orbits in Certain Simple Real Rank Zero C* -algebras
Autor: Ping Wong Ng, Paul Skoufranis
Publikováno v: Canadian Journal of Mathematics. 69:1109-1142
In this paper, we characterize the closures of convex hulls of unitary orbits of self-adjoint operators in unital, separable, simple C* -algebras with non-trivial tracial simplex, real rank zero, stable rank one, and strict comparison of projections

The corona algebra of the stabilized Jiang–Su algebra
Autor: Huaxin Lin, Ping Wong Ng
Publikováno v: Journal of Functional Analysis. 270:1220-1267
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 ( Z ⊗ K ) / Z ⊗ K has real rank zero. We actually prove a more general result.

A relative bicommutant theorem: the stable case of Pedersen's question
Autor: Thierry Giordano, Ping Wong Ng
In 1976, D. Voiculescu proved that every separable unital sub-C*-algebra of the Calkin algebra is equal to its (relative) bicommutant. In his minicourse (see reference), G. Pedersen asked in 1988 if Voiculescu's theorem can be extended to a simple co

The kernel of the determinant map on certain simple $C^*$-algebras
Autor: Ping Wong Ng
Publikováno v: Journal of Operator Theory. 71:341-379
Let A be a unital separable simple C*-algebra such that either (1) A has real rank zero, strict comparison and cancellation or (2) A is TAI. We study the kernel of the de la Harpe--Skandalis determinant on GL^0(A), proving that the determinant vanish
