On split exact sequences and KK-equivalences of amplified graph C*-algebras
AI总结:
本文提出构建放大图C*-代数拆分精确序列的方法,进而构造与C*-代数类相关的显式KK等价性,包括量子Grassmannian。
摘要:
我们提供了一种通用方法,用于构建具有汇点的放大图C*-代数的拆分精确序列。这使得我们能够为一大类C*-代数构造显式KK等价性,包括量子Grassmannian Gr_q(2,4)。我们讨论了与已知(量子)CW构造的兼容性,并给出了经典与量子射影空间C P^1和C P_q^1之间的显式KK等价性。
英文摘要:
We give a general methodology for constructing split exact sequences of amplified graph C*-algebras with sinks. This in turn allows us to construct explicit KK-equivalences with $\mathbb{C}^N$ for a large class of C*-algebras, including the quantum Grassmannian $\mathrm{Gr}_q(2,4)$. We discuss compatibility with known (quantum) CW-constructions and give an explicit KK-equivalence between the classical and quantum projective spaces $\mathbb{C}P^1$ and $\mathbb{C}P_q^1$.
