原子格效应代数的几乎正交性和Hausdorff区间拓扑

Almost orthogonality and Hausdorff interval topologies of atomic lattice effect algebras

Jan Paseka, Zdenka Riecanova, Wu Junde

摘要:

证明了当$E$的所有原子的集合几乎正交时,阿基米德原子格效应代数$E$的区间拓扑是Hausdorff的.在这种情况下,$E$是阶连续的。此外,如果$E$是完整的,那么$E$的元素网的顺序收敛是拓扑的,因此它与顺序拓扑中的收敛一致,并且这个拓扑是紧的Hausdorff相容的,与$E$上对应于紧和余紧元素的分离函数族引起的一致性相容。对于块有限阿基米德原子格效应代数,证明了几乎正交性与s-紧生成的等价性。作为主要应用,我们得到了这些效应代数的状态涂抹定理,以及$\oplus$ -运算在序拓扑和区间拓扑上的连续性。

英文摘要:

We prove that the interval topology of an Archimedean atomic lattice effect algebra $E$ is Hausdorff whenever the set of all atoms of $E$ is almost orthogonal. In such a case $E$ is order continuous. If moreover $E$ is complete then order convergence of nets of elements of $E$ is topological and hence it coincides with convergence in the order topology and this topology is compact Hausdorff compatible with a uniformity induced by a separating function family on $E$ corresponding to compact and cocompact elements. For block-finite Archimedean atomic lattice effect algebras the equivalence of almost orthogonality and s-compact generation is shown. As the main application we obtain the state smearing theorem for these effect algebras, as well as the continuity of $\oplus$-operation in the order and interval topologies on them.
