On $ℓ$ -open $C^{}$ algebras and $ℓ$ -closed $C^{}$ -algebras

Dolapo Oyetunbi, Aaron Tikuisis

In this paper, we characterize $ℓ$ -open and $ℓ$ -closed $C^{*}$ -algebras and deduce that $ℓ$ -open $C^{*}$ -algebras are $ℓ$ -closed, as conjectured by Blackadar. Moreover, we…

On the structure of the Cuntz semigroup in (possibly) nonunital C*-algebras

Aaron Tikuisis, Andrew Toms

We examine the ranks of operators in semi-finite C*-algebras as measured by their densely defined lower semicontinuous traces. We first prove that a unital simple C*-algebra whose…
