Nuclearity and CPC*-systems

Kristin Courtney, Wilhelm Winter

We write arbitrary separable nuclear C*-algebras as limits of inductive systems of finite-dimensional C*-algebras with completely positive connecting maps. The characteristic featu…

The diagonal dimension of sub-C*-algebras

Kang Li, Hung-Chang Liao, Wilhelm Winter

We introduce diagonal dimension, a version of nuclear dimension for diagonal sub-C*-algebras (sometimes also referred to as diagonal C*-pairs). Our concept has good permanence prop…

Nuclear dimension of simple C*-algebras

Jorge Castillejos, Samuel Evington, Aaron Tikuisis +2

We compute the nuclear dimension of separable, simple, unital, nuclear, Z-stable C*-algebras. This makes classification accessible from Z-stability and in particular brings large c…

The Toeplitz algebra has nuclear dimension one

Laura Brake, Wilhelm Winter

We prove the title by constructing 2-colourable completely positive approximations for the Toeplitz algebra. Besides results about nuclear dimension and completely positive contrac…

Structure of nuclear C*-algebras: From quasidiagonality to classification, and back again

Wilhelm Winter

I give an overview of recent developments in the structure and classification theory of separable, simple, nuclear C*-algebras. I will in particular focus on the role of quasidiago…

Rokhlin dimension for flows

Ilan Hirshberg, Gabor Szabo, Wilhelm Winter +1

We introduce a notion of Rokhlin dimension for one parameter automorphism groups of C*-algebras. This generalizes Kishimoto's Rokhlin property for flows, and is analogous to the no…
