Abstract:

We introduce stabilised property $\Gamma$, a $\mathrm {C}^*$-algebraic variant of property $\Gamma$ which is invariant under stable isomorphism. We then show that simple separable nuclear $\mathrm {C}^*$-algebras with stabilised property $\Gamma$ and $\mathrm {Cu}(A) \cong \mathrm {Cu}(A \otimes \mathcal {Z})$ absorb the Jiang-Su algebra $\mathcal {Z}$ tensorially.
