Curry-howard 同构
WebCurry-Howard 同构（Curry-Howard Isomorphism, 有些范畴人倾向叫它 Curry-Howard Correspondence）指出了程序和证明的相似性：一个命题可以看做一个类型，蕴含可以看做函数类型，全称量词可以看做 forall ，否定可以看做没有实例的空类型（Empty Type, Void），析取可以看做和类型 ... http://staff.ustc.edu.cn/~yuzhang/tpl/lecture/lec6.pdf

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 … See more The beginnings of the Curry–Howard correspondence lie in several observations: 1. In 1934 Curry observes that the types of the combinators could be seen as axiom-schemes See more Intuitionistic Hilbert-style deduction systems and typed combinatory logic It was at the beginning a simple remark in Curry and Feys's 1958 book on combinatory logic: the simplest types for the basic combinators K and S of combinatory logic surprisingly … See more Recently, the isomorphism has been proposed as a way to define search space partition in genetic programming.
