WitrynaA Herbrand base of a first-order language L can be constructed from the Herbrand universe of L, by applying to each element of it some predicate from L. It is thus the set of all ground atom s which can be constructed using symbols from L. It is named after Jacques Herbrand.

WitrynaIn , Miller generalizes the concept of the Herbrand expansion to higher order logic, representing the witness information in a tree structure, and explicit transformations between these ‘expansion proofs’ and cut-free sequent proofs are provided. Miller’s presentation of expansion proofs lacked some of the usual features of a formal proof ... Witryna9 maj 2010 · A Herbrand structure I is an answer set [21] of P if I is subset minimal among the structures satisfying gr (P) . Two variations of this semantics, the open [15] and generalised open answer set [16] semantics, consider open domains, thereby relaxing the PNA.

WitrynaHerbrand's theorem is a fundamental result of mathematical logic obtained by Jacques Herbrand (1930). It essentially allows a certain kind of reduction of first-order logic to propositional logic.
