核C *代数具有许多近似性质,最著名的是完全正近似性质。这一点最近得到了改进,以便将传入的映射安排为零阶映射的和。此外,我们还证明了出映射可以被选为渐近阶零。更进一步,当且仅当C * -代数及其所有迹都是拟对角的,这些映射可以被选为渐近相乘的。
Nuclear C∗-algebras enjoy a number of approximation properties, most famously the completely positive approximation property. This was recently sharpened to arrange for the incoming maps to be sums of order-zero maps. We show that, in addition, the outgoing maps can be chosen to be asymptotically order-zero. Further these maps can be chosen to be asymptotically multiplicative if and only if the C∗-algebra and all its traces are quasidiagonal.
