研究了右LCM单关系幺半群和有限型Artin-Tits幺半群的左正则表示生成的C*-代数。我们得到了关于核性、理想结构和纯无限性的结构结果。此外,我们计算K-理论。基于我们的K-理论结果,我们发展了一种计算某些群C*-代数和交叉积的K-理论的新方法。
We study C*-algebras generated by left regular representations of right LCM one-relator monoids and Artin–Tits monoids of finite type. We obtain structural results concerning nuclearity, ideal structure and pure infiniteness. Moreover, we compute K-theory. Based on our K-theory results, we develop a new way of computing K-theory for certain group C*-algebras and crossed products.
