  2. Lambda calculus - Wikipedia

    en.wikipedia.org/wiki/Lambda_calculus

    Lambda calculus is Turing complete, that is, it is a universal model of computation that can be used to simulate any Turing machine. [3] Its namesake, the Greek letter lambda (λ), is used in lambda expressions and lambda terms to denote binding a variable in a function.

  3. Lambda calculus definition - Wikipedia

    en.wikipedia.org/wiki/Lambda_calculus_definition

    The purpose of β-reduction is to calculate a value. A value in lambda calculus is a function. So β-reduction continues until the expression looks like a function abstraction. A lambda expression that cannot be reduced further, by either β-redex, or η-redex is in normal form. Note that alpha-conversion may convert functions.

  4. Free variables and bound variables - Wikipedia

    en.wikipedia.org/wiki/Free_variables_and_bound...

    In the lambda calculus, x is a bound variable in the term M = λx. T and a free variable in the term T. We say x is bound in M and free in T. If T contains a subterm λx. U then x is rebound in this term. This nested, inner binding of x is said to "shadow" the outer binding. Occurrences of x in U are free occurrences of the new x. [3]

  5. Church encoding - Wikipedia

    en.wikipedia.org/wiki/Church_encoding

    In mathematics, Church encoding is a means of representing data and operators in the lambda calculus. The Church numerals are a representation of the natural numbers using lambda notation. The method is named for Alonzo Church, who first encoded data in the lambda calculus this way.

  7. Curry–Howard correspondence - Wikipedia

    en.wikipedia.org/wiki/Curry–Howard_correspondence

    Howard's correspondence naturally extends to other extensions of natural deduction and simply typed lambda calculus. Here is a non-exhaustive list: Girard-Reynolds System F as a common language for both second-order propositional logic and polymorphic lambda calculus, higher-order logic and Girard's System F ω; inductive types as algebraic ...

  9. Calculus - Wikipedia

    en.wikipedia.org/wiki/Calculus

    In addition to differential calculus and integral calculus, the term is also used for naming specific methods of computation or theories that imply some sort of computation. Examples of this usage include propositional calculus, Ricci calculus, calculus of variations, lambda calculus, sequent calculus, and process calculus.
