我们定义了效应代数中的扭转元,并用它来表征链完备效应代数中的MV效应代数和0齐次效应代数。作为一个应用,我们证明了正交完全齐次原子效应代数的每个元素都具有唯一的基本分解为锐元素和非锐原子倍数之和。此外,我们通过正交完全原子效应代数中所有尖锐元素的集合来表征同质性。
We define the torsion element in effect algebras and use it to characterize MV-effect algebra and 0-homogeneous effect algebras in chain-complete effect algebras. As an application, we prove that every element of an orthocomplete homogeneous atomic effect algebra has a unique basic decomposition into a sum of a sharp element and unsharp multiples of atoms. Further, we characterize homogeneity by the set of all sharp elements in orthocomplete atomic effect algebras.
