Maximal UHF subalgebras of certain C*-algebras
Nasser Golestani, Saeid Maleki Oche
A well-known result in dynamical systems asserts that any Cantor minimal system has a maximal rational equicontinuous factor which is in fact an odometer, and reali…
Stable and real rank for crossed products by finite groups
Parisa Elyasi, Nasser Golestani
A long-standing open question in the theory of group actions on C*-algebras is the stable rank of the crossed product. Specifically, N. C. Phillips asked that if a finite group …
Group actions on simple tracially -absorbing C*-algebras
Massoud Amini, Nasser Golestani, Saeid Jamali +1
We show that if is a simple (not necessarily unital) tracially -absorbing C*-algebra and is an action of a finite group on …
Simple tracially -absorbing C*-algebras
Massoud Amini, Nasser Golestani, Saeid Jamali +1
We define a notion of tracial -absorption for simple not necessarily unital C*-algebras, study it systematically, and prove its permanence properties. This extends the…
The Cuntz semigroup and the radius of comparison of the crossed product by a finite group
M. Ali Asadi-Vasfi, Nasser Golestani, N. Christopher Phillips
Let G be a finite group, let A be an infinite-dimensional stably finite simple unital C*-algebra, and let α\colon G \to Aut (A) be an action of G on A which has the weak tracial Ro…
The weak tracial Rokhlin property for finite group actions on simple C*-algebras
Marzieh Forough, Nasser Golestani
We develop the concept of weak tracial Rokhlin property for finite group actions on simple (not necessarily unital) C*-algebras and study its properties systematically. In particul…
