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.
