It is a … WebMay 4, 2016 · Think about what this "law" could possibly mean, computationally. It says, "whenever a conjunction is false, you can find out which conjunct is false". E.g., we know (a, a -> c) -> c, so de Morgan tells us we can decide any proposition a, solve the Halting Problem, you name it.Even if Haskell's polymorphism were not parametric, that would be …
Curry-Howard-Lambek correspondence - HaskellWiki
La correspondance de Curry-Howard, appelée également isomorphisme de Curry-de Bruijn-Howard, correspondance preuve/programme ou correspondance formule/type, est une série de résultats à la frontière entre la logique mathématique, l'informatique théorique et la théorie de la calculabilité. Ils établissent des relations entre les démonstrations formelles d'un système logique et les programmes d'un modèle de calcul.

Web3. The short version of the Curry-Howard correspondence is: to interpret a type as a proposition, interpret the function type a → b as " a implies b ". Interpret the product type a × b as "Both a and b ". Interpret the disjoint union type a ⊔ b as "Either a or b (or both)". Then for example the type of the K combinator, a → ( b → a ...
