The Cuntz semigroup of unital commutative AI-algebras

The Cuntz semigroup of unital commutative AI-algebras

Abstract We provide an abstract characterization for the Cuntz semigroup of unital commutative AI-algebras, as well as a characterization for abstract Cuntz semigroups of the form $\operatorname {\mathrm {Lsc}} (X,\overline {\mathbb {N}})$ for some $T_1$ -space X . In our investigations, we also uncover new properties that the Cuntz semigroup …
