Let CONT be the category of continuous domains and Scott continuous mappings that preserve the way-below relation on domains. Let ω-ALG be the full subcategory of CONT consisting of all countably based algebraic domains, and F I N be the category of finite posets and monotone mappings. The main result proved in this paper is that F I N is the largest Cartesian closed full subcategory of ω-ALG . On the other hand, it is shown that the algebraic L-domains form a Cartesian closed full subcategory of ALG .
