Denotational Versus Declarative Semantics For... →
Denotational semantics is the usual mathematical semantics for functional programming languages. It is higher order (H.O.) in the sense that the semantic domain D includes [D ! D] as a subdomain. On the other hand, the usual declarative semantics for logic programs is first order (F.O.) and given by the least Herbrand model. In this paper, we take a restricted kind of H.O. conditional...
