摘要

Let [X → L] be the set of all continuous mappings from a topological space X to a domain L with the pointwise order. Let Is[X → L], σ[X → L] be the Isbell and Scott topologies on [X → L] respectively. In this paper, the question of when the Isbell and Scott topologies coincide on [X → L] is considered. Main results are: (1) If L is a bicomplete domain, then (ⅰ) Is[X → L] = σ[X→ L] for all core compact spaces X if and only if L is bounded complete; (ⅱ) Is[X → L] = σ[X → L] for all core compact and compact spaces X if and only if L is conditionally bounded complete. (2) Let L be a dcpo consisting of a least element and a decreasing sequence with two lower bounds, then Is[X → L] = σ[X → L) for all core compact spaces X with a countable base. (3) Let X be a well rooted Lawson compact domain and L an FL-domain, then Is[X→L] = σ[X → L].
