In this paper, we present a version of Fraïssé theory for categories of metric structures. Using this version, we show that every UHF algebra can be recognized as a Fraïssé limit of a class of C*-algebras of matrix-valued continuous functions on cubes with distinguished traces. We also give an alternative proof of the fact that the Jiang–Su algebra is the unique simple monotracial C*-algebra among all the inductive limits of prime dimension drop algebras.

广义的 FRAÏSSÉ 极限构式及其在江苏代数中的应用

在本文中,我们提出了用于度量结构类别的 Fraïssé 理论版本。使用这个版本,我们表明每个 UHF 代数都可以被识别为具有显着迹的立方体上的矩阵值连续函数的一类 C*-代数的 Fraïssé 极限。我们还给出了另一个证明,即江苏代数是所有素维降代数的归纳极限中唯一的简单单色 C*-代数。
