Principal Groupoid Models for Cuntz Algebras and their Dynamic Asymptotic Dimension

Samuel Evington, Philipp Sibbel

We compute the dynamic asymptotic dimension of the principal groupoid models for the Cuntz algebras $O_{k}$ for $2 \leq k < \infty$ that have arisen from work of Winter and…

Traces on the uniform tracial completion of $Z$ -stable C*-algebras

Samuel Evington

The uniform tracial completion of a C*-algebra A with compact non-empty trace space T(A) is obtained by completing the unit ball with respect to the uniform 2-seminorm $\|a\|_{2,T(…

Nuclear dimension of extensions of commutative C*-algebras by Kirchberg algebras

Samuel Evington, Abraham C. S. Ng, Aidan Sims +1

We compute the nuclear dimension of extensions of C*-algebras involving commutative unital quotients and stable Kirchberg ideals. We identify the finite directed graphs whose C*-al…

Equivariant $D$ -stability for Actions of Tensor Categories

Samuel Evington, Sergio GirÃ³n Pacheco, Corey Jones

We introduce a notion of equivariant $D$ -stability for actions of unitary tensor categories on C $^{*}$ -algebras. We show that, when $D$ is strongly self-absorbing…
