可分解完全正映射的一个渐近性质与Connes嵌入问题

An asymptotic property of factorizable completely positive maps and the Connes embedding problem

Uffe Haagerup, Magdalena Musat

摘要:

利用可因子分解完全正映射的渐近性质,建立了Connes嵌入问题的一个新形式。我们还证明了Holevo-Werner通道W_n^-是可因子分解的,对于所有不等于3的奇数n.此外,我们还研究了Mendl和Wolf研究的一类信道W_3^+和W_3^-的凸组合的可分解性,并讨论了这类信道的渐近性质.

英文摘要:

We establish a reformulation of the Connes embedding problem in terms of an asymptotic property of factorizable completely positive maps. We also prove that the Holevo-Werner channels W_n^- are factorizable, for all odd integers n different from 3. Furthermore, we investigate factorizability of convex combinations of W_3^+ and W_3^-, a family of channels studied by Mendl and Wolf, and discuss asymptotic properties for these channels.
