The homotopy groups of the automorphism groups of Cuntz-Toeplitz algebras

Taro Sogabe

The Cuntz-Toeplitz algebra $E_{n + 1}$ for $n \geq 1$ is the universal C*-algebra generated by $n + 1$ isometries with mutually orthogonal ranges. In this paper, we investigate the autom…

The group structure of the homotopy set whose target is the automorphism group of the Cuntz algebra

Masaki Izumi, Taro Sogabe

We determine the group structure of the homotopy set whose target is the automorphism group of the Cuntz algebra $O_{n + 1}$ for finite n in terms of K-theory. We show that there is…
