Title QUASI-FREE ACTIONS OF FINITE GROUPS ON THE CUNTZ ALGEBRA $\mathcal{O}_\infty$

Author Pavle Goldstein and Masaki Izumi

(Received November 18, 2010, revised May 20, 2011)
Abstract. We show that any faithful quasi-free actions of a finite group on the Cuntz algebra $\mathcal{O}_\infty$ are mutually conjugate, and that they are asymptotically representable.
