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 $[σ] \in H^{2} (G; T)$ such that $σ (x, y)$ is always a root of unity. We show that the nuclear dimension of the twist…

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…

Central extensions and almost representations

Marius Dadarlat, Forrest Glebe

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

A Cup Product Obstruction to Frobenius Stability

Forrest Glebe

A countable discrete group $Γ$ is said to be Frobenius stable if a function from the group that is "almost multiplicative" in the point Frobenius norm topology is "close" to a genu…
