AF-代数与有理同伦理论
AF-algebras and rational homotopy theory
摘要:
给出了AF-代数的拟酉群的有理同伦群的计算方法。作为应用,我们证明了AF-代数是K-稳定的当且仅当它是有理K-稳定的。
英文摘要:
We give a procedure to compute the rational homotopy groups of the group of quasi-unitaries of an AF-algebra. As an application, we show that an AF-algebra is K-stable if and only if it is rationally K-stable.
