一致Roe代数中的Cartan子代数

Cartan subalgebras in uniform Roe algebras

Stuart White, Rufus Willett

摘要:

本文研究了一致Roe代数的Cartan子代数的结构和唯一性问题。讨论了$\mathrm{C}^*$ -代数的包含$B\subseteq A$与有界几何的度量空间的一致Roe代数$C^*_u(X)$中的$\ell^\infty(X)$的标准包含同构的条件.当$X$粗嵌入到希尔伯特空间时,得到了一致Roe代数内部Roe Cartans直到自同构的唯一性结果;当$X$具有性质A时,得到了一致Roe代数内部Roe Cartans直到内自同构的唯一性结果.

英文摘要:

In this paper we study structural and uniqueness questions for Cartan subalgebras of uniform Roe algebras. We characterise when an inclusion $B\subseteq A$ of $\mathrm{C}^*$-algebras is isomorphic to the canonical inclusion of $\ell^\infty(X)$ inside a uniform Roe algebra $C^*_u(X)$ associated to a metric space of bounded geometry. We obtain uniqueness results for `Roe Cartans' inside uniform Roe algebras up to automorphism when $X$ coarsely embeds into Hilbert space, and up to inner automorphism when $X$ has property A.
