"WebbSolutions to semantic paradoxes often involve restrictions of classical logic for semantic vocabulary. In the paper we investigate the costs of these restrictions in a model case.

Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively-defined data structures such as lists, boxed lists, or trees, which are constructed according to the axioms and rules of inference of the logical system. Consequently, proof theory is syntactic in nature, in contrast to model theory, which is semantic in nature. Webb4 juli 2000 · 1. Residuation. Logic is about logical consequence.As a result, the conditional is a central notion in logic because of its intimate connection with logical consequence. This connection is neatly expressed in residuation condition:. p, q ⊢ r if and only if p ⊢ q → r. It says that r follows from p together with q just when q → r follows from p alone.
