A structural rule in logic, particularly proof theory, governs the manipulation of sequent components. It operates without regard to the…
Proof theory is a branch of mathematical logic focused on the structure and properties of mathematical proofs. It formalizes reasoning,…
A fundamental procedure in proof theory that systematically removes 'cuts' from a proof. This process simplifies proofs and demonstrates that…
A cut rule in proof theory introduces an intermediate conclusion within a deductive proof. This intermediate step is then utilized…
