Mathematical proofRelated: Formalization makes every permitted proof step mechanically checkable.
SoundnessRelated: Soundness constrains what conclusions the system's proofs can establish.
Formal logicBroader topic: A proof makes an inference valid by exhibiting its permitted derivation.
Axiomatic methodRelated: Proofs make the derivation from axioms explicit and checkable.
DerivationRelated: A proof is a derivation whose final statement is the theorem being established.
CompletenessRelated: Provability in a deductive system is witnessed by a formal proof.
