In other words, it is a proof (including all assumptions) that can be written on a large enough sheet of paper. By contrast, infinitary logic studies logics that allow infinitely long … See more In mathematics and logic, an operation is finitary if it has finite arity, i.e. if it has a finite number of input values. Similarly, an infinitary operation is one with an infinite number of input values.

WebA few years later, Gentzen gave a consistency proof for Peano arithmetic. The only part of this proof that was not clearly finitary was a certain transfinite induction up to the ordinal ε 0. If this transfinite induction is accepted as a finitary method, then one can assert that there is a finitary proof of the consistency of Peano arithmetic.

WebThe proof of Theorem F.4 poses, however, fascinating technical problems since the cut elimination usually takes place in infinitary calculi. A cut-free proof of a \(\Sigma^0_1\) statement can still be infinite and one needs a further “collapse” into the finite to be able to impose a numerical bound on the existential quantifier.
