WebOct 1, 2015 · I've been studying the lambda calculus and recently saw the Church-Rosser theorem. The theorem states that when applying reduction rules to terms in the lambda calculus, the ordering in which the reductions are chosen does not make a difference to the eventual result (from wiki). But I find this inconsistent with call-by-value reduction and ... WebApr 1, 1995 · Abstract. The notion of parallel reduction is extracted from the simple proof of the Church-Rosser theorem by Tait and Martin-L f. Intuitively, this means to reduce a number of redexes (existing in a -term) simultaneously. Thus in the case of -reduction the effect of a parallel reduction is same as that of a "complete development" which is ...

We prove the theorem for β -equality, namely, if M l r N then M → m P ← n N for some term P and some natural numbers m, n.
WebAccording to the Church-Rosser theorem, if two different reduction strategies both lead to an answer, then they will lead to the same answer. So the answers to the second and third questions are no with the following caveat: any reduction strategy that leads to an answer will give the same answer. The key here is whether or not the strategy ... Weban important subclass of such reductions will be treated (Theorem 3).
