Abstract. In this paper, the notions of regular, completely regular, compact additive generalized algebraic lattices ([7]) are introduced, and Stone compactification is constructed. The following theorem is also obtained. Theorem: An additive generalized algebraic lattice has a Stone compactification if and only if it is regular and completely regular.2000 AMS Classification: 06B30, 06B35, 54D35, 54H10
“…On the other hand, suppose (X, C) is a co-topological space and C the set of all closed subsets of a topological space on X. D. Drake, W. J. Thron, S. Papert considered C as a complete lattice (C, ∪, ∩, ∅, X)( [11,16]). But unfortunately the correspondence between complete lattices and T 0 -topological spaces is not one-to-one.…”

In this paper, with the additivity property ([8]), the generalized way-below relation ([15]) and the maximal system of subsets ([6]) as tools, we prove that all lower homomorphisms between two additive generalized algebraic lattices form an additive generalized algebraic lattice, which yields the classical theorem: the function space between T0-topological spaces is also a T0-topological space with respect to the pointwise convergence topology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
