Motivated by an observation of Namioka and Phelps on an approximation property of order unit spaces, we introduce the [Formula: see text]-tensor product and the [Formula: see text]-tensor product of two compact matrix convex sets. We define a new approximation property for operator systems, and give a characterization using the [Formula: see text]- and [Formula: see text]-tensor products in the spirit of Grothendieck. Thus, an operator system has the operator system approximation property if and only if it is [Formula: see text]-nuclear in a natural sense.

算子系统的近似属性

受 Namioka 和 Phelps 对阶单位空间近似性质的观察启发,我们介绍了两个紧凑矩阵凸集的 [公式:见文本]-张量积和 [公式:见文本]-张量积。我们为算子系统定义了一个新的近似属性,并本着格洛腾迪克的精神使用 [Formula: see text]- 和 [Formula: see text]-张量积给出了表征。因此,一个算子系统具有算子系统近似属性当且仅当它是[公式:见正文]-自然意义上的核。
