论文摘要
我们在免费产品的包含和完全正面地图的扩展方面使用结果来确定上三角形$ 3 \ times 3 $矩阵的最大$ c^*$。我们在较大的上三角矩阵和与循环图相关的图形代数的背景下考虑了这些相同的结果。
We use results on inclusions of free products and extensions of completely positive maps to determine the maximal $C^*$-envelope for upper triangular $3 \times 3$ matrices. We consider these same results in the context of larger upper triangular matrices and graph algebras associated to cycle graphs.
