Rohlin flows on the Cuntz algebra $O_{\infty}$

Ola Bratteli, Akitaka Kishimoto, Derek W. Robinson

It is shown that certain quasi-free flows on the Cuntz algebra $O_{\infty}$ have the Rohlin property and therefore are cocycle-conjugate with each other. This, in particular, shows t…

Approximate AF flows

Akitaka Kishimoto

When $α$ is a flow on a unital AF algebra $A$ such that there is an increasing sequence of finite-dimensional $α$ -invariant C*-subalgebras of $A$ with dense union, we call $α$ an A…
