A C*-diagonal in the Jiang-Su algebra via entangled matrix cones
Lukas Obermeyer, Wilhelm Winter
We construct the Jiang-Su algebra Z as an inductive limit of dimension drop algebras, describing the latter as entangled matrix cones to explicitly define the connecting *-homomorp…

Images of Order Zero Maps
Kristin Courtney, Wilhelm Winter
We give sufficient conditions allowing one to build a C*-algebraic structure on a self-adjoint linear subspace of a C*-algebra in such a way that the subspace is naturally identifi…
