Cuntz代数及其不动点代数的循环自同构

On the cyclic automorphism of the Cuntz algebra and its fixed-point algebra

Valeriano Aiello, Stefano Rossi

摘要:

研究了生成等距的轮换作用下$\mathcal{O}_n$的不动点代数的结构.证明了它与$\mathcal{O}_n$是$*$ -同构的,从而推广了Choi和Latrémolière关于$\mathcal{O}_2$的一个结果.作为该方法的一个应用,我们还描述了交换自同构下$\mathcal{O}_{2n}$的不动点代数.

英文摘要:

We investigate the structure of the fixed-point algebra of $\mathcal{O}_n$ under the action of the cyclic permutation of the generating isometries. We prove that it is $*$-isomorphic with $\mathcal{O}_n$, thus generalizing a result of Choi and Latrémolière on $\mathcal{O}_2$. As an application of the technique employed, we also describe the fixed-point algebra of $\mathcal{O}_{2n}$ under the exchange automorphism.
