Lambda-Calculus and Combinators – J Roger Hindley – Bok

One note: That printf requires the arguments to be cast into void * to make the code strictly compliant (gcc -pedantic). lambda calculus logic is the same as in boolean logic. in lamba calculus there are no values, only symbols (names). TRUE is not only function, but also a name that describes it. and when the result of evaluation is λab.a, it's not important it's a function, more important is it's a function described by symbol TRUE. – rsm Oct 17 '17 at 9:26 The lambda calculus extends the idea of an expression language to include func-tions.

Lambda calculus

Lambda calculus (λ-calculus), originally created by Alonzo Church, is the world's smallest programming language. Despite not having  The lambda calculus was developed in the 1930s by Alonzo Church (1903–1995 ), one of the leading developers of mathematical logic. · The lambda calculus was   Lambda calculus as described above seems to permit functions of a single variable only. The abstraction mechanism allows for only one parameter at a time .

If you can perform these reduction operations, you can do lambda calculus. A lambda calculus term consists of: Variables, which we can think of as leaf nodes holding strings. Applications, which we can think of as internal nodes.

Then consider A = f(5), in the lambda calculus we just write A = (λx.x2)(5).
