The Church-Rosser property in symmetric combinatory logic

A reduction rule that satisfies the Church–Rosser property has the property that every term M can have at most one distinct normal form, as follows: if X and Y are normal forms of M then by the Church–Rosser property, they both reduce to an equal term Z. Both terms are already normal forms so . [4] See more In lambda calculus, the Church–Rosser theorem states that, when applying reduction rules to terms, the ordering in which the reductions are chosen does not make a difference to the eventual result. More precisely, if … See more In 1936, Alonzo Church and J. Barkley Rosser proved that the theorem holds for β-reduction in the λI-calculus (in which every abstracted variable must appear in the term's body). … See more The Church–Rosser theorem also holds for many variants of the lambda calculus, such as the simply-typed lambda calculus, many calculi with advanced type systems, and Gordon Plotkin's beta-value calculus. Plotkin also used a Church–Rosser theorem to prove … See more One type of reduction in the pure untyped lambda calculus for which the Church–Rosser theorem applies is β-reduction, in which a subterm of the form $${\displaystyle (\lambda x.t)s}$$ is contracted by the substitution See more Webas the Church-Rosser property.

WebPlotkin also used a Church–Rosser theorem to prove that the evaluation of functional programs (for both lazy evaluation and eager evaluation) is a function from programs to values (a subset of the lambda terms).

Similarly, the combinatory logic that is based on a combinatorially complete base and its dual is not confluent (cf. Meyer et al. (1998)).
