The Y combinator is an implementation of a fixed-point combinator in lambda calculus. Fixed-point combinators may also be easily defined in other functional and imperative languages. The implementation in lambda calculus is more difficult due to limitations in lambda calculus. The fixed-point combinator may … See more In mathematics and computer science in general, a fixed point of a function is a value that is mapped to itself by the function. In combinatory logic for computer science, a fixed-point … See more Fixed-point combinators can be used to implement recursive definition of functions. However, they are rarely used in practical programming. See more (The Y combinator is a particular implementation of a fixed-point combinator in lambda calculus. Its structure is determined by the limitations of lambda calculus. It is not necessary or helpful to use this structure in implementing the fixed-point … See more Because fixed-point combinators can be used to implement recursion, it is possible to use them to describe specific types of recursive computations, such as those in fixed-point iteration See more In the classical untyped lambda calculus, every function has a fixed point. A particular implementation of fix is Curry's paradoxical combinator Y, represented by $${\displaystyle {\textsf {Y}}=\lambda f.\ (\lambda x.f\ (x\ x))\ (\lambda x.f\ (x\ x))\ .}$$ See more The Y combinator, discovered by Haskell B.
