Classification of homomorphisms from to a C*-algebra
Leonel Robert, Luis Santiago
A class of C*-algebras is described for which the homomorphism from to the algebra may be classified by means of the Cuntz semigroup functor. Examples are given of algeb…

The cone of lower semicontinuous traces on a C*-algebra
George A. Elliott, Leonel Robert, Luis Santiago
The cone of lower semicontinuous traces is studied with a view to its use as an invariant. Its properties include compactness, Hausdorffness, and continuity with respect to inducti…

Cuntz semigroups of ideals and quotients and a generalized Kasparov Stabilization Theorem
Alin Ciuperca, Leonel Robert, Luis Santiago
Let A be a C*-algebra and I a closed two-sided ideal of A. We use the Hilbert C*-modules picture of the Cuntz semigroup to investigate the relations between the Cuntz semigroups of…
