TīmeklisSyntax of the Lambda Calculus The lambda calculus derives its usefulness from having a sparse syntax and a simple semantics, and yet it retains sufﬁcient power to represent all com-putable functions. Lambda expressions come in four varieties: 1. Variables, which are usually taken to be any lowercase letters. TīmeklisLambda calculus (also written as λ-calculus) is a formal system in mathematical logic for expressing computation based on function abstraction and application using variable binding and substitution.It is a universal model of computation that can be used to simulate any Turing machine.It was first introduced by mathematician Alonzo Church …
