UHF $L^p$ -算子代数的不可分类性

Nonclassifiability of UHF $L^p$-operator algebras

Eusebio Gardella, Martino Lupini

摘要:

我们证明了简单的,可分的,monotracial UHF $L^{p}$ -算子代数是不可分类的(完全)同构使用可数结构,如K-理论数据,作为不变量。同样的断言成立,即使只考虑UHF $L^{p}$ -算子代数的张量积型从对角系统的相似性。对于$p=2$,可以得出可分的非自伴UHF算子代数不能用直到(完全)同构的可数结构来分类。我们的结果回答了N.克里斯托弗·菲利普斯(Christopher Phillips)依赖博雷尔复杂性理论,特别是赫约斯的湍流理论。

英文摘要:

We prove that simple, separable, monotracial UHF $L^{p}$-operator algebras are not classifiable up to (complete) isomorphism using countable structures, such as K-theoretic data, as invariants. The same assertion holds even if one only considers UHF $L^{p}$-operator algebras of tensor product type obtained from a diagonal system of similarities. For $p=2$, it follows that separable nonselfadjoint UHF operator algebras are not classifiable by countable structures up to (complete) isomorphism. Our results, which answer a question of N. Christopher Phillips, rely on Borel complexity theory, and particularly Hjorth's theory of turbulence.
