... Logical Equivalences for Predicates We can define valid, satisfiable and unsatisfiable in the same manner as with propositional logic. Let F be a formula of a first order language L. We say F is: 1. valid or a tautology if it is satisfied by every interpretation of L 2. satisfiable if some interpre ...

Normalised and Cut-free Logic of Proofs
... [2001]. The logic of proofs Lp is a natural extension of classical propositional logic by means of proof-carrying formulas. The operations on proofs in the logic of proofs suffice to recover the explicit provability of modal and intuitionistic logic. We can prove many results about Lp: e.g. the dedu ...
