Selfless Inclusions of C*-Algebras

Ben Hayes, Srivatsav Kunnawalkam Elayavalli, Gregory Patchell +1

We introduce and study a natural notion of selflessness for inclusions of C*-probability spaces, which in particular implies that all intermediate C*-algebras are selfless in the s…

Products of commutators in simple algebras

Matej Brešar, Hau-Yuan Jang, Leonel Robert

Let $A$ be a finite-dimensional simple algebra that is not a field. We show that every $a \in A$ can be written as $a = (b c - c b) (d e - e d)$ for some $b, c, d, e \in A$ . This is not always tru…

Selfless reduced free product $C^{*}$ -algebras

Ben Hayes, Srivatsav Kunnawalkam Elayavalli, Leonel Robert

We study selflessness in the general setting of reduced free products of $C^{*}$ -algebras. Towards this end, we develop a suitable theory of rapid decay for filtrations in arbitrary…

Classification of homomorphisms from $C_{0} (0, 1]$ to a C*-algebra

Leonel Robert, Luis Santiago

A class of C*-algebras is described for which the homomorphism from $C_{0} (0, 1]$ to the algebra may be classified by means of the Cuntz semigroup functor. Examples are given of algeb…
