WebMar 12, 2014 · We prove a general theorem stating that no dual combinatory system possesses the Church-Rosser property. Although the lack of confluence might be problematic in some cases, it is not a problem per se. In particular, we show that no damage is inflicted upon the structurally free logics, the system in which dual combinators first … WebMar 24, 2024 · The Church-Rosser theorem states that lambda calculus as a reduction system with lambda conversion rules satisfies the Church-Rosser property.

Webcalculus lacks the Church-Rosser property. Similarly, the combinatory logic that is based on a combinatorially complete base and its dual is not confluent (cf. Meyer et al. (1998)). A short while ago the present author proved that dual combinatory logic lacks the Church-Rosser property in a much broader sense, namely, if there WebAlonzo Church and J. Barkley Rosser proved in 1936 that lambda calculus has this property; hence the name of the property. (The fact that lambda calculus has this property is also known as the Church–Rosser theorem.) In a rewriting system with the Church–Rosser property the word problem may be reduced to the search for a …

WebA Thue system T is Church-Rosser if, for every choice of x and y, x <-sy implies that for some z, xSz and ySz. Intuitively, in a Church-Rosser Thue system T, if two strings are reduced (using the replacement rules of S) to two distinct irreducible strings, then the two strings are not congruent. Partially supported by NSF Grant MCS-8211621. Weba strong form of a theorem stated by Church and Rosser [5] proving the consistency of the λ-calculus. The Church-Rosser property of the untyped λ-calculus w.r.t. β-reduction can be stated as follows: for any λ-terms M,M 1,M 2 such that M →∗ β M 1 and M →∗ β M 2 there exists M 3 such that M 1 →∗β M 3 and M 2 →∗β M 3 ...
WebFeb 27, 1991 · The above proof shows that the Church-Rosser property, which is a property belonging to all terms, even to those not capable of being typed, can be proved by an argument proper to the typable terms. The proof uses all the heavy apparatus of Girard's proof of normalizability. In [5] and [4], the case of normal:zability becomes less heavy by ...
