本文证明Shalit-Shamovich谱半径唯一决定算子空间结构,回答相关猜想,并推广至最小谱半径,应用于非交换函数代数的完全有界同构问题。
AI 中文摘要
我们证明了Shalit和Shamovich引入的谱半径唯一地确定了底层的算子空间结构:若E_1和E_2是C^d上的算子空间结构,且相应的谱半径ρ_{E_1}和ρ_{E_2}在每一个d元算子组上一致,则恒等映射是完全等距的。这回答了Scherer、Shalit和Shamovich的一个问题。此外,我们获得了关于最小谱半径的类似结果,并展示了其在算子空间单位球上有界非交换函数代数的完全有界同构问题中的一个应用。
英文摘要
We show that the spectral radius introduced by Shalit and Shamovich uniquely determines the underlying operator space structure: If E_1 and E_2 are operator space structures on C^d such that the corresponding spectral radii ρ_{E_1} and ρ_{E_2} agree on every d-tuple of operators, then the identity map is completely isometric. This answers a question of Scherer, Shalit and Shamovich. Moreover, we obtain an analogous result for the minimal spectral radii, and showcase an application to the completely bounded isomorphism problem for algebras of bounded non-commutative functions on operator space unit balls.
