本文讨论了Cuntz代数的可遗传C^*-子代数.给出了Cuntz代数的在同构意义下所有的可遗传C^*-子代数,完整解答了Cuntz代数上的矩阵代数的同构问题,并讨论了某些纯无限单的C^*-代数的可遗传C^*-子代数.
We discuss isomorphism of hereditary C^*-subalgebras of Cuntz algebra. We give all the hereditary C^*-subalgebras of Cuntz algebra (matrix algebras over Cuntz algebra) up to isomorphism, and hence completely solve the isomorphism problem of hereditary C^*-subalgebras of Cuntz algebra. Hereditary C^*-subalgebras of certain purely infinite simple C^*-algebras are also discussed.
