WitrynaHerbrand Semantics. Herbrand logic differs from first-order logic solely in the structures it considers to be models. The semantics of a given set of sentences is defined to be the set of Herbrand models that satisfy it, for a given vocabulary. Definition (Herbrand Model): A Herbrand model for vocabulary V is any set of ground atoms in V. WitrynaHerbrand structures have the advantage, computationally speaking, of being guided by the defin-ability of all elements in them.

In first-order logic, a Herbrand structure S is a structure over a vocabulary σ that is defined solely by the syntactical properties of σ. The idea is to take the symbols of terms as their values, e.g. the denotation of a constant symbol c is just "c" (the symbol). It is named after Jacques Herbrand. Herbrand … Zobacz więcej Definition The Herbrand universe serves as the universe in the Herbrand structure. 1.

Let ϕ be an arbitrary first-order sentence. Then ϕ is satisfiable iff Θpr,sk(ϕ) has a Herbrand model. Proof. Let ψ , Θpr,sk(ϕ). If ψ has a model, Herbrand or not, then ψ is satisfiable.
