Perforation conditions and almost algebraic order in Cuntz semigroups

Ramon Antoine, Francesc Perera, Henning Petzka

For a C${}^{\ast }$-algebra $A$, it is an important problem to determine the Cuntz semigroup $\mathrm{Cu}(A\otimes \mathcal{Z})$ in terms of $\mathrm{Cu}(A)$. We approach this problem from…
