摘要:

1994年, Foulis和Bennett在表示不可精确测量的量子逻辑结构时引入了效应代数. 该文用直接构造的方法, 给出一类效应代数上的态表示定理. 即, 若Ω是紧的 Hausdorff 拓扑空间, 令E(Ω)={f: C(Ω), 0 ≤ f  ≤ 1}, 则 φ 是(E(Ω), Ο, 0, 1) 上的态当且仅当 Ω 上存在唯一的正则Borel  概率测度μ使得对每个f (E(Ω), Ο, 0, 1), φ (f)=∫Ω f dμ.

Abstract:

In 1994, Foulis and Bennett introduced effect algebra to represent the unsharp quantum logic structure.  In this
paper, using the direct construction method, the authors present a state representation theorem of a class of effect algebras. That is, if Ω is a compact Hausdorff topological space, E(Ω)= {f: f ∈C(Ω, 0 ≤ f ≤ 1, then φ is a state of the effect algebra (E(Ω), Ο, 0, 1) if there exists a unique regular Borel probability measure μ on Ω such that for each f (E(Ω), Ο, 0, 1), φ (f) = ∫ Ω dμ.

Key words: Effect algebras, States, Representation theorem
