  • lambda abstraction — A term in lambda-calculus denoting a function. A lambda abstraction begins with a lower-case lambda (represented as "\" in this document), followed by a variable name (the "bound variable"), a full stop and a lambda expression (the body). The body is taken to extend as far to the right as possible so, for example an expression, \ x . \ y . x+y is read as \ x . (\ y . x+y). A nested abstraction such as this is often abbreviated to: \ x y . x + y The lambda expression (\ v . E) denotes a function which takes an argument and returns the term E with all free occurrences of v replaced by the actual argument. Application is represented by juxtaposition so (\ x . x) 42 represents the identity function applied to the constant 42. A lambda abstraction in Lisp is written as the symbol lambda, a list of zero or more variable names and a list of zero or more terms, e.g. (lambda (x y) (plus x y)) Lambda expressions in Haskell are written as a backslash, "\", one or more patterns (e.g. variable names), "->" and an expression, e.g. \ x -> x.
