Isometric Actions are Quasidiagonal
Samantha Pilgrim
We show every isometric action is quasidiagonal in a strong sense. This shows that reduced crossed products by such actions are quasidiagonal or MF whenever the reduced algebra of…

Dynamic Asymptotic Dimension of Translation Actions on Compact Lie Groups
Samantha Pilgrim
We develop a method to bound the dynamic asymptotic dimension of isometric group actions in terms of the asymptotic dimension of a space of graphs similar to…
