算子效应代数$\varepsilon (H)$上序列积的唯一性问题

The Uniqueness Problem of Sequence Product on Operator Effect Algebra $\varepsilon (H)$

Liu Weihua, Wu Junde

摘要:

量子效应是满足$0\leq A\leq I$的复希尔伯特空间$H$上的算子。我们用${\cal E}(H)$表示所有量子效应的集合。本文证明了关于${\cal E}(H)$上的序列积理论的定理4.3,该定理表明,实际上存在${\cal E}(H)$上不具有广义Lüders形式的序列积。这个结果否定地回答了一个古德的开放问题。

英文摘要:

A quantum effect is an operator on a complex Hilbert space $H$ that satisfies $0\leq A\leq I$. We denote the set of all quantum effects by ${\cal E}(H)$. In this paper we prove, Theorem 4.3, on the theory of sequential product on ${\cal E}(H)$ which shows, in fact, that there are sequential products on ${\cal E}(H)$ which are not of the generalized Lüders form. This result answers a Gudder's open problem negatively.
