Moves on $k$ -graphs preserving Morita equivalence

Caleb Eckhardt, Kit Fieldhouse, Daniel Gent +3

We initiate the program of extending to higher-rank graphs ( $k$ -graphs) the geometric classification of directed graph $C^{*}$ -algebras, as completed in the 2016 paper of Eilers, Res…

Finite decomposition rank for virtually nilpotent groups

Caleb Eckhardt, Elizabeth Gillaspy, Paul McKenney

We show that inductive limits of virtually nilpotent groups have strongly quasidiagonal C*-algebras, extending results of the first author on solvable virtually nilpotent groups. W…

Free groups and quasidiagonality

Caleb Eckhardt

We use free groups to settle a couple questions about the values of the Pimsner-Popa-Voiculescu modulus of quasidiagonality for a set of operators $Ω$ , denoted by qd $(Ω)$ . Along th…
