The untyped Lambda Calculus
... Note: there is no way to define identifiers for function - the numbers used above are no symbolic identifiers but only shorthands. In reality, a lambda expression is nothing more than a long sequence of variables, abstractions and applications - one has to replace each of this identiiers with the co ...

... Beta reduction must not be permitted to do variable capture. If capture would occur, use alpha conversion first to rename variables. When as many beta reductions as possible have been applied, the resulting expression is in normal form. CSE 341 -- S. Tanimoto Lambda Calculus ...
