Nuclear dimension and sums of commutators
Leonel Robert
The problem of expressing a selfadjoint element that is zero on every bounded trace as a finite sum (or a limit of sums) of commutators is investigated in the setting of C*-algebra…

Nuclear dimension and Z-stability of non-simple C*-algebras
Leonel Robert, Aaron Tikuisis
We investigate the interplay of the following regularity properties for non-simple C*-algebras: finite nuclear dimension, Z-stability, and algebraic regularity in the Cuntz semigro…
