Nuclear Dimension of Twisted -Algebras of Virtually Abelian Groups
Forrest Glebe, Pradyut Karmakar, Iason Moutzouris
Let be a finitely generated virtually abelian group and such that is always a root of unity. We show that the nuclear dimension of the twist…
On Chern classes of almost representations
Marius Dadarlat, Forrest Glebe
For a discrete group , we study vector bundles on compact subsets of associated to almost representations . We compute the first Chern class of in…
Vanishing of Topological Invariants For Unnormalized Schatten 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 -algebras we construct a canonical central extension of the unitary group b…
A Cup Product Obstruction to Frobenius Stability
Forrest Glebe
A countable discrete group 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…
Frobenius Non-Stability of Nilpotent Groups
Forrest Glebe
A countable discrete group is said to be Frobenius stable if every function from the group to unitary matrices that is "almost multiplicative" in the Frobenius norm is "close" to a…
A Constructive Proof that Many Groups with Non-Torsion 2-Cohomology are Not Matricially Stable
Forrest Glebe
A discrete group is matricially stable if every function from the group to a complex unitary group that is "almost multiplicative" in the point-operator norm topology is "close" to…
Enumerating linear systems on graphs
Sarah Brauner, Forrest Glebe, David Perkinson
The divisor theory of graphs views a finite connected graph as a discrete version of a Riemann surface. Divisors on are formal integral combinations of the vertices of ,…
