Church encoding lambda
http://gregfjohnson.com/pred/ WebNATURAL NUMBERS --- MICHAELSON'S ENCODING As mentioned above, Church resorts to a nesting of pair functions to allow computation of pred. Here we abandon Church and go right to the treatment in our text: def zero = identity def succ = λ n.λ s.((s false) n) This choice models numbers as functions with selector arguments.

WebWhat is Church encoding? With lambda calculus, all we get out of the box are variables, function abstraction, and function application. Essentially we have a language where the only primitive data type is a function! …
WebAccording to Church, a. function is a rule of correspondence by which when anything is given (as argument) another thing (the value of the function for that argument) may be obtained. (1941 [BE: 201]) The λ-calculi are essentially a family of notations for representing functions as such rules of correspondence rather than as graphs (i.e., sets ...
WebThe simply typed lambda calculus (), a form of type theory, is a typed interpretation of the lambda calculus with only one type constructor that builds function types.It is the canonical and simplest example of a typed lambda calculus.
