Nuclear Dimension of Twisted $C^{*}$ -Algebras of Virtually Abelian Groups

Forrest Glebe, Pradyut Karmakar, Iason Moutzouris

Let $G$ be a finitely generated virtually abelian group and $[I ¨ ] \in H^{2} (G; T)$ such that $I ¨ (x, y)$ is always a root of unity. We show that the nuclear dimension of the twi…

Vanishing of Topological Invariants For Unnormalized Schatten $p$ multiplicative Maps

Forrest Glebe

A result of Dadarlat shows that nonzero even rational cohomology obstructs the matricial stability of many discrete groups. In the author's previous work, 2-cohomology is used to a…

On Chern classes of almost representations

Marius Dadarlat, Forrest Glebe

For a discrete group $I^$ , we study vector bundles $E_{I ¨} $ on compact subsets of $B I^$ associated to almost representations $I ¨ : I^ \to U (n)$ . We compute the first Chern class of $E_Ï…

Central extensions and almost representations

Marius Dadarlat, Forrest Glebe

For a sequence of unital tracial $C^{*}$ -algebras $(A_{n}, I ¨ _{n}),$ we construct a canonical central extension of the unitary group $U (ℓ^{\infty} (N, A_{n}) / c_{0} (N, A_{n}))$ …
