In proof theory, proof nets are a geometrical method of representing proofs that eliminates irrelevant syntactical features of regular proof calculi such as the natural deduction calculus and the sequent calculus; by this means the formal properties of proof identity correspond more closely to the intuitively desirable properties. Proof nets were introduced by Jean-Yves Girard.
