Extensions of C*-algebas by a small ideal
Huaxin Lin, Ping Wong Ng
We classify all essential extensions of the form $$0 \rightarrow \W \rightarrow \D \rightarrow A \rightarrow 0$$ where $\W$ is the unique separable simple C*-algebra with a unique…
Remarks on Essential Codimension
Jireh Loreaux, Ping W. Ng
We look for generalizations of the Brown-Douglas-Fillmore essential codimension result, leading to interesting local uniqueness theorems in -theory. We also study the structure…
Purely infinite corona algebras
Victor Kaftal, P. W. Ng, Shuang Zhang
Let A be a simple, sigma-unital, non-unital C*-algebra, with metrizable tracial simplex T(A), which is projection-surjective and injective and has strict comparison of positive ele…
A relative bicommutant theorem: the stable case of Pedersen's question
Thierry Giordano, Ping W. 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. Pederse…
The minimal ideal in multiplier algebras
Victor Kaftal, P. W. Ng, Shuang Zhang
Let be a simple, -unital, non-unital, non-elementary C*-algebra and let be the intersection of all the ideals of that properly co…
Closed convex hulls of unitary orbits in certain simple real rank zero C-algebras
Ping Wong Ng, Paul Skoufranis
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…
