摘要: Nuclear C*-algebras enjoy a number of approximation properties, most famously the completely positive property. This was recently sharpened to arrange for incoming maps be sums order-zero maps. We show that, in addition, outgoing can chosen asymptotically order-zero. Further these multiplicative if and only C*-algebra all its traces are quasidiagonal.
