Proof and computation rules

For ap(f ; a), first reduce f , if it becomes a function term, λ(x.b), then reduce the function term to b[a/x], that is, substitute the argument a for the variable x in the body of the function b and continue computing. If it does not reduce to a function, then no furt ...

Curry–Howard correspondence
![](https://commons.wikimedia.org/wiki/Special:FilePath/Coq_plus_comm_screenshot.jpg?width=300)
In programming language theory and proof theory, the Curry–Howard correspondence (also known as the Curry–Howard isomorphism or equivalence, or the proofs-as-programs and propositions- or formulae-as-types interpretation) is the direct relationship between computer programs and mathematical proofs. It is a generalization of a syntactic analogy between systems of formal logic and computational calculi that was first discovered by the American mathematician Haskell Curry and logician William Alvin Howard. It is the link between logic and computation that is usually attributed to Curry and Howard, although the idea is related to the operational interpretation of intuitionistic logic given in various formulations by L. E. J. Brouwer, Arend Heyting and Andrey Kolmogorov (see Brouwer–Heyting–Kolmogorov interpretation) and Stephen Kleene (see Realizability). The relationship has been extended to include category theory as the three-way Curry–Howard–Lambek correspondence.
