Perforation conditions and almost algebraic order in Cuntz semigroups
Ramon Antoine, Francesc Perera, Henning Petzka
For a C-algebra , it is an important problem to determine the Cuntz semigroup in terms of . We approach this problem from…
Comparison Properties of the Cuntz semigroup and applications to C*-algebras
Joan Bosa, Henning Petzka
We study comparison properties in the category Cu aiming to lift results to the C*-algebraic setting. We introduce a new comparison property and relate it to both the CFP and -c…
Corrigendum to "Regularity for stably projectionless, simple C*-algebras"
Henning Petzka, Aaron Tikuisis
An error is identified and corrected in the construction of a non-Z-stable, stably projectionless, simple, nuclear C*-algebra carried out in a paper by the second author.
Geometric Structure of Dimension Functions of Certain Continuous Fields
Ramon Antoine, Joan Bosa, Francesc Perera +1
In this paper we study structural properties of the Cuntz semigroup and its functionals for continuous fields of C*-algebras over finite dimensional spaces. In a variety of cases,…
The Blackadar-Handelman theorem for non-unital C*-algebras
Henning Petzka
A well-known theorem of Blackadar and Handelman states that every unital stably finite C*-algebra has a bounded quasitrace. Rather strong generalizations of stable finiteness to th…
On certain multiplier projections
Henning Petzka
Let $\MCZK$, denote the multiplier algebra over $\CZK$, the algebra of continuous functions into the compact operators with spectrum the infinite product of two-spheres. We conside…
